Metastatic Seminoma with Positive Staining of Cytokeratin and MOC31: A Diagnostic Pitfall

Retroperitoneal metastasis of seminoma often occurs in the higher stage through lymph nodes. Generally, seminoma expresses specific germ cell markers while being negative for carcinoma markers. We present a unique case of cytokeratin positive seminoma initially presented as retroperitoneal metastasis. The diagnosis was made based on the histological features and immunohistochemical stains. Testicular ultrasound confirmed the primary tumor in the patient’s left testicle. Pathologists should always be aware of germ cell tumors when encountering a metastasis of an unknown primary.

A Rare Case of a Solitary Fibrous Tumor of the Spermatic Cord

Solitary fibrous tumors (SFTs) are rare mesenchymal tumors, originally identified in the pleura. Even though they have subsequently been described in several extrapleural sites, the incidence of SFTs in the spermatic cord is particularly rare. Here, we report a case of a 27-year-old male that presented with a 3-year history of left scrotal swelling. Computed tomography (CT) and ultrasound demonstrated multiple solid, hypoechoic well-circumscribed masses that were separate from the testis. Surgical excision of the mass led to pathologic diagnosis of a solitary fibrous tumor involving the spermatic cord. Solitary fibrous tumors, although rare, are an important differential diagnosis for urogenital tumors.

Leiomyosarcoma of the Renal Vein Mimicking a Primitive Renal Cell Carcinoma: Case Report of an Unusual Presentation

Primary leiomyosarcomas (LMS) of vascular origin are rare tumors, and more than half of the cases arise in the inferior vena cava (IVC). Primary LMS of the renal vein are extremely rare tumors with only a few cases reported in the literature. Their diagnosis is made only by pathological features. Histologically, they are made of atypical spindle-shaped cells arranged in long intersecting fascicles. Tumor cells stain positive for myogenic markers in immunohistochemistry. Standard treatment consists of radical nephrectomy followed by chemotherapy and/or radiotherapy. Because of insufficient histological data and follow-up, the prognosis factors are not well identified. Overall prognosis of renal vein LMS is poor. We report here an exceptional case of a huge LMS of the right renal vein mimicking a primitive renal cell carcinoma, occurring in a 56-year-old male patient.

A Rare Case of Endometriosis of the Small Bowel

Endometriosis of the small bowel is a rare clinical event. The clinical condition presents with vague abdominal symptoms and is usually not diagnosed acutely, unless clinicians have a high index of suspicion. Most patients are diagnosed after multiple clinical encounters. We present a case of endometriosis causing small bowel obstruction diagnosed postsurgically.

A Review Leveraging a Rare and Unusual Case of Basal Cell Carcinoma of the Prostate

Basal cell carcinoma (BCC) is a rare nonacinar variant of prostatic carcinoma. In spite of prostatic acinar adenocarcinoma being one of the most common carcinomas in prostate, <100 prostatic BCC cases have been reported to date. Adenoid cystic/cribriform histology has been described in varying proportions to occur in prostatic BCC and is reported to be associated with aggressive behavior and high risk of metastasis. Herein, we present a case of prostatic BCC with adenoid cystic morphology, comprehensively describe its immunohistochemical and MYB/MYBL1 gene rearrangement findings, discuss its differential diagnosis, and review the literature of this rare entity.

Colonic Metastasis of Adenoid Cystic Carcinoma 19 Years after the Primary Tumor Resection

Adenoid cystic carcinoma (ACC) is a tumor characterized by slow growth and late distant metastasis. The lung and breast are the most common sites for metastasis. Colonic metastasis of such a tumor is rare, with few case reports available. Here, we report a case of ACC arising from minor salivary gland that metastasized to the colon 19 years after the primary tumor resection, with literature review of the clinical, histological, and molecular features of ACC. This case raises our awareness of such tumors as a differential diagnosis of colorectal cancer.
