Primary Intracranial Melanoma with Early Leptomeningeal Spread: A Case Report and Treatment Options Available Wed, 29 Jul 2015 12:56:04 +0000 http://www.hindawi.com/journals/crionm/2015/293802/ Primary CNS melanomas are rare and they constitute about 1% of all cases of melanomas and 0.07% of all brain tumors. These tumors are aggressive in nature and may metastasise to other organs. Till date less than 25 cases have been reported in the literature. The primary treatment for local intraparenchymal tumours is complete resection and/or radiotherapy and it is associated with good survival. However once there is disease spread to leptomeninges the overall median survival is around 10 weeks. In this case report we describe a primary intracranial melanoma without any dural attachment in 16-year-old boy who had radical excision of the tumor followed by radiotherapy who eventually had rapidly developed leptomeningeal disease and review the literature with a focus on the clinic pathological, radiological, and treatment options.

Two Cases of Pneumatosis Intestinalis during Cetuximab Therapy for Advanced Head and Neck Cancer Wed, 29 Jul 2015 06:40:20 +0000 http://www.hindawi.com/journals/crionm/2015/214236/ Pneumatosis intestinalis is a rare but known potential complication of treatment with cetuximab. Here we present two cases of pneumatosis intestinalis occurring in patients who were receiving cetuximab as treatment for advanced head and neck cancer. In both cases, cetuximab was discontinued after discovery of the pneumatosis intestinalis. James A. Miller, Daniel J. Ford, Mohamed S. Ahmed, and Thom R. Loree Copyright © 2015 James A. Miller et al.

Small Bowel Adenocarcinoma as the Cause of Gastrointestinal Bleeding in Celiac Disease: A Rare Malignancy in a Common Disease Tue, 28 Jul 2015 10:22:00 +0000 http://www.hindawi.com/journals/crionm/2015/865383/ Introduction. Celiac disease is associated with an increased risk of small bowel malignancies, particularly lymphoma. Its association with small bowel carcinoma is less known. Case Description. We report a case of an 89-year-old woman with celiac disease who experienced recurrent episodes of gastrointestinal bleeding and was ultimately found to have adenocarcinoma of the small intestine. Discussion and Evaluation. Diagnosis of small bowel adenocarcinoma is often delayed because of the need for specialized modalities, which are often deferred in the inpatient setting. Although resection is the modality of choice for small bowel tumors, a majority is either locally advanced or metastatic at diagnosis, and even localized cancers have worse prognosis than stage-matched colorectal tumors. The role of adjuvant chemotherapy is uncertain, but it is often offered extrapolating data from other gastrointestinal cancers. Small bowel carcinomas occurring in the context of celiac disease appear to be associated with higher rates of microsatellite instability than sporadic tumors, although other specific genomic abnormalities and mechanisms of carcinogenesis in celiac disease remain unknown. Conclusion. Recurrent episodes of gastrointestinal bleeding in a patient with celiac disease should prompt an early evaluation of the small bowel to assure timely diagnosis of carcinoma at an early curable stage.

Alveolar Rhabdomyosarcoma in a 69-Year-Old Woman Receiving Glucagon-Like Peptide-2 Therapy Wed, 22 Jul 2015 11:30:30 +0000 http://www.hindawi.com/journals/crionm/2015/107479/ A 69-year-old woman was diagnosed with alveolar rhabdomyosarcoma (ARMS) of the nasopharynx. She has a history of catastrophic thromboembolic event in the abdomen that caused short-gut syndrome and dependence on total parenteral nutrition (TPN) twelve hours per day. She was treated for short-gut syndrome with teduglutide, a glucagon-like peptide-2 (GLP-2) analog, which led to reduction of TPN requirements. However, a few months later, she developed metastatic alveolar rhabdomyosarcoma. Though a causative relationship is unlikely between the peptide and ARMS due to the brief time course between teduglutide therapy and sarcoma diagnosis, neoplastic growth may have been accelerated by the GLP-2 analog, causing release of IGF-1. The transmembrane receptor for IGF-1 is frequently overexpressed in ARMS and is implicated in cell proliferation and metastatic behavior. This case describes a rare incidence of metastatic alveolar rhabdomyosarcoma in a sexagenarian and possibly the first case reported associated with the use of teduglutide. Teduglutide was discontinued due to a potential theoretical risk of acceleration of sarcoma growth, and the patient’s rhabdomyosarcoma is in remission following sarcoma chemotherapy. Laura E.

A Case of Primary Breast Diffuse Large B-Cell Lymphoma Treated with Chemotherapy Followed by Elective Field Radiation Therapy: A Brief Treatment Pattern Review from a Radiation Oncologist’s Point of View Mon, 13 Jul 2015 13:25:47 +0000 http://www.hindawi.com/journals/crionm/2015/907978/ We here report a case of primary breast lymphoma (PBL). A 44-year-old woman presented with a painless mass in the right breast. Fine needle aspiration cytology and excisional biopsy were performed. Excisional biopsy revealed low grade lymphoma, which was subsequently confirmed with histopathology and diagnosed as diffuse large B-cell lymphoma (DLBCL). A chest computed tomography scan revealed a 3.5 cm sized breast mass with skin thickening and a small sized lymphadenopathy in the ipsilateral axilla. Radiation therapy including the right whole breast and ipsilateral axilla and supraclavicular lymph node was performed after the patient received four courses of R-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone plus rituximab) chemotherapy. At the follow-up period of 42 months, the patient is surviving with no evidence of disease. No morbidities occurred in this patient during the follow-up period. We also briefly review the current practice pattern in PBL patients with DLBCL.

Small Cell Lung Cancer Patient with Profound Hyponatremia and Acute Neurological Symptoms: An Effective Treatment with Fludrocortisone Thu, 09 Jul 2015 11:09:20 +0000 http://www.hindawi.com/journals/crionm/2015/286029/ Hyponatremia is a frequent electrolyte abnormality in patients with small cell lung cancer (SCLC). Being usually asymptomatic, hyponatremia may cause symptoms like nausea, fatigue, disorientation, headache, muscle cramps, or even seizures, particularly if severe and rapid decrease of serum sodium levels occurs. Here we report a case of SCLC patient with severe hyponatremia and acute neurological symptoms that developed 2 days after the first course of second-line chemotherapy, most probably due to the release of antidiuretic hormone (ADH, also known as arginine vasopressin) during lysis of the tumour cells. Initial treatment consisted of continuous administration of hypertonic saline that resulted in improvement of patient’s neurological status. However, to obtain a persistent increase in serum sodium level, pharmacological intervention with oral fludrocortisone 0.1 mg twice daily was needed. We can therefore conclude that mineralocorticoids may be used to correct hyponatremia in SCLC patients when appropriate. Jana Jaal, Tõnu Jõgi, and Alan Altraja Copyright © 2015 Jana Jaal et al.

Denileukin Diftitox (Ontak) as Maintenance Therapy for Peripheral T-Cell Lymphomas: Three Cases with Sustained Remission Thu, 09 Jul 2015 10:21:58 +0000 http://www.hindawi.com/journals/crionm/2015/123756/ Peripheral T-cell lymphomas (PTCL) are rare but markedly aggressive forms of non-Hodgkin’s lymphoma (NHL). They carry a poor prognosis, with current therapeutic approach being generally ineffective. The most employed first-line treatment is CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone), which still results in high rates of relapses. Denileukin diftitox is a fusion protein combining the cytotoxic portion of the diphtheria toxin and the receptor-binding domain of the interleukin-2 (IL-2) molecule, thereby targeting cells expressing the IL-2 receptor, including both T-cell and B-cell lymphomas. It has been approved for the treatment of cutaneous T-cell lymphomas, and it has documented activity in PTCL both as a single agent and as part of combination therapy. This report documents three cases of PTCL where denileukin diftitox has been used as long-term maintenance therapy after complete remission was achieved. While the overall survival rate of patients with advanced stage, refractory PTCL is generally poor (with median overall survival of 5.5 months), the three patients described in this report are all experiencing an ongoing complete remission for more than four years.

Lung Metastasis Mimicking Fingertip Infection Tue, 07 Jul 2015 10:47:56 +0000 http://www.hindawi.com/journals/crionm/2015/708789/ Metastasis fingers (acral metastasis) are finding a poor prognosis. Past medical history should be questioned and metastasis from primary tumor should be kept in mind in patients with pain, swelling, and hyperemia in fingers. Successful surgical treatment on acral metastasis does not extend the life expectancy; however, it reduces the patient’s pain during his terminal period, saves the functions of the limb, and increases life comfort.

Secretory Carcinoma of the Breast: Report of Two Cases and Review of the Literature Sun, 05 Jul 2015 08:03:09 +0000 http://www.hindawi.com/journals/crionm/2015/581892/ Secretory carcinoma of the breast is an extremely rare subtype of breast cancer characterized by intracellular or extracellular secretion and granular eosinophilic cytoplasm of the neoplastic cells. The disease which was considered to be predominant in younger age group has been recognized in adult population too and tends to show slow growth and indolent behavior. The disease occurs preferentially in females and only 27 cases have been reported amongst males. An optimal treatment for the disease subtype has been debated because of the paucity of data. We report two cases (one female and one male) of this rare disease that underwent treatment at our institution.

Antiangiogenic Therapies and Extracranial Metastasis in Glioblastoma: A Case Report and Review of the Literature Tue, 23 Jun 2015 08:57:58 +0000 http://www.hindawi.com/journals/crionm/2015/431819/ We present a case report of a patient with glioblastoma multiforme (GBM) complicated by extracranial metastasis (ECM) whose survival of nearly four years surpassed the anticipated life expectancy given numerous negative prognostic factors including EGFRvIII-mutation, unmethylated MGMT promoter status, and ECM. Interestingly, while this patient suffered from locally aggressive disease with multiple intracranial recurrences, the proximal cause of death was progressive extracranial disease and complications related to pulmonary metastases. Herein, we review potential mechanisms of ECM with an emphasis upon glioblastoma molecular and genetic profiles and the potential implications of targeted agents such as bevacizumab. Mohamed H.

Embryonal Carcinoma in Cryptorchid Abdominal Testis of an Infant Sun, 07 Jun 2015 08:19:33 +0000 http://www.hindawi.com/journals/crionm/2015/383241/ Cryptorchidism is a known predisposing factor for the development of testicular tumors in adults. Age of patient at the time of treatment of undescended testes has some bearing on the risk of neoplasia. Testicular neoplasia at the time of primary surgery for cryptorchidism has been reported rarely in prepubertal period. We report a case where embryonal carcinoma was detected in a cryptorchid testis of an infant. Atia Zaka-ur-Rab, Zeeba Zaka-ur-Rab, and Kafil Akhtar Copyright © 2015 Atia Zaka-ur-Rab et al.

Malignant Triton Tumors in Sisters with Clinical Neurofibromatosis Type 1 Sun, 31 May 2015 14:07:18 +0000 http://www.hindawi.com/journals/crionm/2015/405351/ Malignant triton tumors (MTTs) are rare and aggressive sarcomas categorized as a subgroup of malignant peripheral nerve sheath tumors (MPNSTs). MTTs arise from Schwann cells of peripheral nerves or existing neurofibromas and have elements of rhabdomyoblastic differentiation. We report the occurrence of MTTs in two sisters. The first patient is a 36-year-old female who presented with left sided chest wall swelling. She also had clinical features consistent with neurofibromatosis type 1 (NF-1). Debulking of the mass showed high-grade malignant peripheral nerve sheath tumor with skeletal muscle differentiation (MTT). The patient was treated with ifosfamide and adriamycin along with radiation. Four years after treatment, she still has no evidence of disease recurrence. Her sister subsequently presented to us at the age of 42 with left sided lateral chest wall pain. Imaging showed a multicompartmental retroperitoneal cystic mass with left psoas involvement. The tumor was resected and, similarly to her sister, it showed high-grade malignant peripheral nerve sheath tumor with rhabdomyoblastic differentiation (MTT). The patient was started on chemotherapy and radiation as described above. Basnet Alina, Jofre A. Sebastian, and Capo Gerardo Copyright © 2015 Basnet Alina et al. All rights reserved. Synchronous Multicentric Giant Cell Tumour of Distal Radius and Sacrum with Pulmonary Metastases Wed, 27 May 2015 09:03:38 +0000 http://www.hindawi.com/journals/crionm/2015/354158/ Giant cell tumour (GCT) is an uncommon primary bone tumour, and its multicentric presentation is exceedingly rare. We report a case of a 45-year-old female who presented to us with GCT of left distal radius. On the skeletal survey, osteolytic lesion was noted in her right sacral ala. Biopsy confirmed both lesions as GCT. Pulmonary metastasis was also present. Resection-reconstruction arthroplasty for distal radius and thorough curettage and bone grafting of the sacral lesion were done. Multicentric GCT involving distal radius and sacrum with primary sacral involvement is not reported so far to our knowledge.

Primary Mediastinal Synovial Sarcoma Presenting as Superior Vena Cava Syndrome: A Rare Case Report and Review of the Literature Mon, 25 May 2015 06:52:21 +0000 http://www.hindawi.com/journals/crionm/2015/651813/ Primary mediastinal sarcomas are aggressive tumors with a very rare incidence. This report describes the case of a 35-year-old male patient who presented with acute symptoms of dyspnoea, facial puffiness, voice-hoarseness, and engorged neck veins. With the clinical picture consistent with the superior vena cava (SVC) syndrome, the patient was investigated with computed tomography of the chest. This revealed a large soft tissue density mass lesion compressing the SVC along with other critical superior mediastinal structures. Histopathological evaluation of the mass revealed features consistent with a soft tissue sarcoma and positive staining was observed for vimentin and S-100. Cytogenetic analysis by fluorescent in situ hybridisation (FISH) demonstrated the t(X:18) translocation. Thus diagnosis was established as primary mediastinal synovial sarcoma. Patient was treated with three cycles of neoadjuvant chemotherapy, to which there was a partial response as per the RECIST criteria. Surgical excision of the mediastinal mass was performed, and further postoperative treatment with adjuvant chemoradiotherapy was provided. Patient currently is free of disease. This is to the best of our knowledge the first report in the world literature of a successfully treated case of “primary mediastinal sarcomas presenting as SVC syndrome.” Patient is under regular surveillance at our clinic and remains free of recurrence one year after treatment completion.

Chemotherapy in the Setting of Severe Liver Dysfunction in Patients with Metastatic Colorectal Cancer Thu, 21 May 2015 11:39:12 +0000 http://www.hindawi.com/journals/crionm/2015/420159/ The liver is the dominant site of metastases for patients with metastatic colorectal cancer (mCRC). Depending on the timing of diagnosis and the biology of the disease, it is not uncommon for these patients to present with visceral crisis in the form of severe liver dysfunction. Treatment of these individuals is, however, difficult and challenging. The decision to consider chemotherapy in these dire circumstances entails consideration of numerous factors. If we were to focus on just the metabolism of the different drugs and biologic agents available to treat mCRC, both 5-fluorouracil and oxaliplatin alone or in combination with a monoclonal antibody are reasonable choices. Specifically, FOLFOX is a feasible and safe option in patients with mCRC with severe liver dysfunction. Choice of the biologic agent to add to the doublet chemotherapy could be individualized based on the RAS status and the clinical scenario. Based on the divergent experience of treating 2 cases and other prior reports, a summary of recommendations with a model in the form of a “therapeutic triad” is presented. The paper highlights the therapeutic challenges in patients with mCRC and severe liver dysfunction. The choice of chemotherapeutic agents and reports of other cases/series is also presented.

Prolonged Complete Response in a Patient with Metastatic Pancreatic Adenocarcinoma after FOLFIRINOX Chemotherapy and Maintenance with FOLFIRI Thu, 21 May 2015 07:08:51 +0000 http://www.hindawi.com/journals/crionm/2015/659624/ Metastatic pancreatic adenocarcinoma confers a poor prognosis. Even with recent advances in the treatment of this disease with the introduction of two modestly effective chemotherapy regimens, complete responses are still very rare. Moreover, there are no published data on how to further manage the patients who achieve a sustained remission following treatment. Herein, we report the case of a patient with metastatic pancreatic adenocarcinoma who achieved a complete response lasting for more than three years after receiving induction chemotherapy with FOLFIRINOX followed by maintenance with FOLFIRI.

Multidisciplinary Approach to Hepatic Metastases of Intracranial Hemangiopericytoma: A Case Report and Review of the Literature Mon, 18 May 2015 06:38:30 +0000 http://www.hindawi.com/journals/crionm/2015/214306/ Hemangiopericytoma is a rare primary tumor originating from Zimmerman’s pericytes, with significant metastatic potential. Hepatic metastatic disease requires an aggressive approach by a multidisciplinary team of dedicated oncology specialists, to prolong survival in selected patients. We report on a patient with recurrent hepatic metastases of grade II intracranial hemangiopericytoma 5 years after initial treatment, managed by a stepwise combination of liver resection, radiofrequency ablation, and transarterial embolization. Although metastatic disease implies hematogenous dissemination, long-term survival after liver resection has been reported and major hepatectomies are justified in patients with adequate local control. Liver resections combined with transarterial embolization are highly recommended, due to hypervascularity of the tumor. Dimitrios K. Manatakis, Spiridon G.

Metastasis-Induced Acute Pancreatitis Successfully Treated with Chemotherapy and Radiotherapy in a Patient with Small Cell Lung Cancer Thu, 14 May 2015 12:41:52 +0000 http://www.hindawi.com/journals/crionm/2015/304279/ Although involvement of pancreas is a common finding in small cell lung cancer (SCLC), metastasis-induced acute pancreatitis (MIAP) is very rare. A 50-year-old female with SCLC who had limited disease and achieved full response after treatment presented with acute pancreatitis during her follow-up. The radiologic studies revealed a small area causing obliteration of the pancreatic duct without mass in the pancreatic neck, and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) confirmed the metastasis of SCLC. The patient was treated successfully with systemic chemotherapy and radiotherapy delivered to pancreatic field. In SCLC, cases of MIAP can be encountered with conventional computed tomography with no mass image, and positron emission tomography and EUS-FNA can be useful for diagnosis of such cases. Aggressive systemic and local treatment can prolong survival, especially in patients with good performance status.

Synchronous Orbital and Gastrointestinal Metastases from Breast Cancer: A Case Report and Review of Literature Wed, 13 May 2015 11:20:15 +0000 http://www.hindawi.com/journals/crionm/2015/282790/ Breast cancer is the most common malignancy among women and is a significant cause of morbidity and mortality worldwide. With the advent of improved imaging techniques and screening programmes, only a small proportion of women present with metastatic disease. Metastases involving the gastrointestinal (GI) tract and orbit are rare occurrences. We describe the case of a woman with simultaneous GI and orbital metastases from breast cancer who initially presented with abdominal pain and blurred vision and also summarise a review of the literature.

A Case of Biphasic Pulmonary Blastoma Treated with Carboplatin and Paclitaxel plus Bevacizumab Wed, 13 May 2015 09:16:57 +0000 http://www.hindawi.com/journals/crionm/2015/842621/ Background. Pulmonary blastoma is a rare lung tumor similar to fetal lung tissues. Surgical resection at early stage is more curative than other treatments, but there is no standard treatment in unresectable cases. We show a case treated with carboplatin and paclitaxel plus bevacizumab. Case. A 68-year-old man received surgical resection and was diagnosed with biphasic pulmonary blastoma (pT3N0M0 stage IIB). Metastasis to the spleen was detected six weeks after the surgery. Carboplatin, paclitaxel, and bevacizumab were administered and showed an effect on the metastasis. Four courses of the chemotherapy were completed, but a metastasis was found and the metastatic tumor in the spleen was enlarged. After that, chemotherapy was not effective afterward and he died of the progression of biphasic pulmonary blastoma on the 292nd day of illness. Conclusion. In this case, chemotherapy with carboplatin and paclitaxel plus bevacizumab was temporarily efficacious for biphasic pulmonary blastoma.

Oxaliplatin-Induced Pulmonary Toxicity in Gastrointestinal Malignancies: Two Case Reports and Review of the Literature Sun, 10 May 2015 07:02:10 +0000 http://www.hindawi.com/journals/crionm/2015/341064/ Oxaliplatin is a common chemotherapy drug, used mainly for colon and gastric cancer. Most common side effects are peripheral sensory neuropathy, hematological toxicity, and allergic reactions. A less common side effect is pulmonary toxicity, characterized mainly by interstitial pneumonitis. The incidence of this side effect is unknown, but the toxicity can be fatal. Twenty-six cases of pulmonary toxicity have been described in the literature, seven in the setting of adjuvant treatment. We describe two fatal cases of pulmonary injury related to oxaliplatin and a review of the literature. Mor Moskovitz, Mira Wollner, and Nissim Haim Copyright © 2015 Mor Moskovitz et al.

A Case Report of Long-Term Survival following Hepatic Arterial Infusion of L-Folinic Acid Modulated 5-Fluorouracil Combined with Intravenous Irinotecan and Cetuximab Followed by Hepatectomy in a Patient with Initially Unresectable Colorectal Liver Metastases Wed, 06 May 2015 11:04:40 +0000 http://www.hindawi.com/journals/crionm/2015/472037/ A 43-year-old women admitted to our hospital for weight loss, anorexia, and abdominal pain was diagnosed with sigmoid neoplasm and multiple bilobar liver metastases. This patient received six cycles of systemic FOLFOX prior to a laparoscopically assisted anterior resection of the rectosigmoid for a poorly differentiated invasive adenocarcinoma T2N2M1, K-RAS negative (wild type). Hepatic arterial infusion (HAI) of L-folinic acid modulated 5-fluorouracil (LV/5-FU) with intravenous (iv) irinotecan (FOLFIRI) and cetuximab as adjuvant therapy resulted in a complete metabolic response (CR) with CEA normalization. A right hepatectomy extended to segment IV was performed resulting in (FDG-)PET negative remission for 7 months. Solitary intrahepatic recurrence was effectively managed by local radiofrequent ablation following 6c FOLFIRI plus cetuximab iv. Multiple lung lesions and recurrence of pulmonary and local lymph node metastases were successfully treated with fractionated stereotactic radiotherapy (50 Gy) and iv LV/5-FU/oxaliplatin (FOLFOX) plus cetuximab finally switched to panitumumab with CR as a result. At present the patient is in persistent complete remission of her stage IV colorectal cancer, more than 5 years after initial diagnosis of the advanced disease. Multidisciplinary treatment with HAI of chemotherapy (LV/5-FU + CPT-11) plus EGFR-inhibitor can achieve CR of complex unresectable LM and can even result in hepatectomy with possible long-term survival.

Effective Downsizing of a Large Oesophageal Gastrointestinal Stromal Tumour with Neoadjuvant Imatinib Enabling an Uncomplicated and without Tumour Rupture Laparoscopic-Assisted Ivor-Lewis Oesophagectomy Tue, 05 May 2015 12:12:26 +0000 http://www.hindawi.com/journals/crionm/2015/165736/ Neoadjuvant imatinib for gastrointestinal stromal tumours (GISTs) is increasingly used nowadays. As oesophagectomy is associated with high morbidity and mortality, a preoperative downsizing of an oesophageal GIST to limit the extent of resection would be ideal. Because these tumours are rare and neoadjuvant treatment with imatinib is recent, there is limited literature available regarding neoadjuvant administration of imatinib in patients with oesophageal GISTs. A 50-year-old woman presented with total dysphagia. An upper endoscopy and biopsy revealed a large submucosal KIT-positive GIST obstructing the mid oesophagus. CT confirmed a lesion measuring 99 mm × 50 mm × 104 mm. Because the size and location of the tumour increased the risk of intraoperative rupture, it was decided to administer preoperative imatinib. The patient had an excellent clinical and radiological response. Her dysphagia gradually resolved and the follow-up CT scans of the first 10 months showed a gradually reducing tumour size to 54 mm × 33 mm × 42 mm. The patient underwent an uneventful laparoscopic-assisted Ivor-Lewis oesophagectomy. Postoperatively, the patient continued with adjuvant imatinib. At the last follow-up, 1 year from operation and 38 months from the diagnosis, the patient is disease free.

A Rare Case of Undifferentiated Carcinoma of the Colon with Rhabdoid Features: A Case Report and Review of the Literature Thu, 30 Apr 2015 18:44:25 +0000 http://www.hindawi.com/journals/crionm/2015/531348/ Malignant rhabdoid tumors were originally described in children. Subsequently, the same histological pattern was described in adults. Malignant rhabdoid tumors are aggressive neoplasms that have been reported in multiple organs. To our best knowledge, only 16 previous cases of rhabdoid tumor in the colon have been described in the literature. We present the case of an 87-year-old lady who was diagnosed with a rhabdoid tumor of the colon that relapsed rapidly after surgical resection. The literature concerning this unusual neoplasm was subsequently reviewed with comparison of all known cases in the literature. E. Moussaly and J. P. Atallah Copyright © 2015 E. Moussaly and J. P.

A Rare Initial Presentation of Gastric Cancer with Multiple Osteolytic Lesions Thu, 23 Apr 2015 07:04:18 +0000 http://www.hindawi.com/journals/crionm/2015/689431/ Gastric cancer is the 12th leading cause of cancer-related deaths in the United States and commonly metastasizes to the bones. However, the presentation of gastric cancer as bony metastases without preceding gastrointestinal symptoms is rare which has been infrequently reported in the literature. Moreover, leptomeningeal carcinomatosis is an unusual complication of gastric cancer accounting for less than 1 percent of these patients. We present a unique case of a middle aged male who presented to the emergency department with worsening backache which started one month priorly. The only abnormal laboratory test was an elevated alkaline phosphatase of 154 IU/L. The imaging of his spine showed osteolytic lesions which on biopsy revealed signet ring cells. A small 2 cm ulcerated mass was found on esophagogastroduodenoscopy at the gastric cardia which on biopsy revealed signet ring gastric carcinoma. The patient received chemotherapy with capecitabine and oxaliplatin as well as radiation and showed a good response initially. A few months later, he presented with persistent worsening headaches and on brain imaging was found to have leptomeningeal carcinomatosis. Ten months after the diagnosis of gastric carcinoma, he passed away.

Aggressive angiomyxoma is a rare, slowly growing, and benign tumour of mesenchymal origin, which affects women of reproductive age and is associated with a high risk of local recurrence. Case Presentation. A case of a 47-year-old white female is presented herein, with a large polypoid, gelatinous mass on the right labia majora, measuring 26 × 21 × 6 cm. Histopathologically, the lesion was composed of spindle and stellate-shaped cells embedded in a myxoid matrix. Another specific feature was the presence of variable-sized thin-walled capillaries and thick-walled vascular channels. The patient underwent wide local excision of the tumour with clear margins and developed local recurrence 18 months later. Discussion. Aggressive angiomyxoma of the vulva needs to be distinguished from benign myxoid tumors with a low risk of local recurrence as well as from malignant myxoid neoplasms. Usually wide local excision with tumour-free margins and occasionally hormonal manipulation is the treatment of choice.

Phyllodes Tumor of the Breast Metastasizing to the Vulva Wed, 15 Apr 2015 12:54:08 +0000 http://www.hindawi.com/journals/crionm/2015/589547/ Phyllodes tumors of the breast are rare breast tumors that resemble fibroadenoma. They are composed of two types of tissues: stromal and glandular tissues. Unlike fibroadenoma, they are commonly found in the third decade of life and they tend to grow more rapidly. Depending on the relative components of the cells and mitotic activity, they are classified into benign, borderline, and malignant. They are usually present as a lump in the breast. Phyllodes tumors are usually managed by wide excision. The excision should be wide enough to ensure a tumor-free margin. Recurrence rate is very high and most recurrences are usually local. Metastasis to the vulva has not been reported. Olusegun Kayode Ajenifuja, Nonna Kolomeyevskaya, Fadi Habib, Adekunle Odunsi, and Shashikant Lele Copyright © 2015 Olusegun Kayode Ajenifuja et al.

Diagnostic Challenges in Primary Hepatocellular Carcinoma: Case Reports and Review of the Literature Wed, 01 Apr 2015 07:31:48 +0000 http://www.hindawi.com/journals/crionm/2015/878763/ Hepatocellular carcinoma is the fifth most common malignancy and the third leading mortality cause worldwide. It typically develops secondarily to liver cirrhosis, due to hepatitis B or C infection, alcohol abuse, metabolic disease, and so forth. According to the American Association for the Study of Liver Diseases (AASLD) guidelines, which constitute diagnostic standards, the diagnosis of primary hepatocellular carcinoma (HCC) should be based on contrast-enhanced imaging. Lesion hyperenhancement should be observed throughout the arterial phase, followed by the washout during the venous phase. The diagnosis can also be based on the histopathological evaluation of liver biopsy specimen. Although the standards are clear, we often see patients with advanced HCC in clinical practice, who cannot be offered any effective treatment. Patients with chronic liver disease, presenting with inconclusive and changeable test results, constitute a separate problem. In such cases the diagnostic process is typically long-term and delayed. In this paper we present three case reports where the diagnosis could not be made promptly and the patients died as a result of a delayed diagnostic process.

Foreign Body Granulomas Induced by Intramuscular Leuprorelin Acetate Injection for Prostate Cancer: Clinical Mimics of Soft Tissue Sarcoma Tue, 31 Mar 2015 13:33:01 +0000 http://www.hindawi.com/journals/crionm/2015/947040/ We describe two cases of florid, foreign body granulomatous reaction occurring in the upper arms of males in their eighth decade, who were undergoing treatment with depot injection of leuprorelin acetate for prostatic carcinoma. These patients presented with rapidly enlarging extremity soft tissue masses and were referred to a tertiary sarcoma center with clinical suspicion of a primary soft tissue neoplasm. The occurrence of injection site granulomas secondary to leuprorelin acetate administration is rarely known outside the urological and dermatological communities, and their recognition is important due to the spectrum of clinical differential diagnoses and potential for diagnostic confusion with metastatic prostatic cancer and primary sarcoma and in order to avoid unnecessary stress and clinical intervention for patients.

False Positive Radioiodinated Metaiodobenzylguanidine (123I-MIBG) Uptake in Undifferentiated Adrenal Malignant Tumor Mon, 30 Mar 2015 12:16:17 +0000 http://www.hindawi.com/journals/crionm/2015/164280/ 123I-Metaiodobenzylguanidine (123I-MIBG) scintigraphy is a widely used functional imaging tool with a high degree of sensitivity and specificity in diagnosis of pheochromocytoma. However, rare cases of false positive reactions have been reported. A 67-year-old male patient was admitted with epigastric pain. Abdominal computed tomography (CT) revealed a heterogeneous left adrenal mass 6 cm in diameter; following hormone testing, 123I-MIBG scintigraphy was performed to determine the presence of pheochromocytoma, which confirmed eccentric uptake by a large left adrenal gland mass. Chest CT and PET-CT confirmed metastatic lymphadenopathy; therefore, endobronchial ultrasound transbronchial needle aspiration was performed. Metastatic carcinoma of unknown origin was suspected from a lymph node biopsy, and surgical resection was performed for definitive diagnosis and correction of excess hormonal secretion. A final diagnosis of undifferentiated adrenal malignant tumor was rendered, instead of histologically malignant pheochromocytoma, despite the uptake of 123I-MIBG demonstrated by scintigraphy.
