Total Penectomy for Recurrent Chordoma of the Corpus Cavernosum
Chordomas are rare low malignant neoplasm arising from remnants of the notochord with predilection site of the clivus or the os sacrum. Standard therapy is radical excision and adjuvant radiation. Due to invasive growth and adjacent to vital structures resection is often incomplete, and therefore, local recurrence is frequent. First, to the best knowledge of our authors, we present a 70-year-old man with a recurrent chordoma infiltrating the corpus cavernosum. Asymptomatic recurrence was diagnosed by magnet resonance imaging according to the standard follow-up. Our interdisciplinary tumor board recommended surgical resection. We performed a total penectomy and perineal urethrostomy to achieve negative resection margins and preserve best quality of life for the patient.
Spontaneous Urethral Laceration in a Patient Experiencing Acute Ulcerative Colitis Flare
Spontaneous urethral laceration in the female without associated external trauma is an exceedingly rare phenomenon. Most cases are related to childbirth or the presence of a concomitant pelvic fracture or penetrating injury. Herein, we present a novel case of spontaneous urethral laceration in a female which happened to occur during an acute flare of her previously diagnosed ulcerative colitis. The diagnosis of spontaneous urethral laceration is rare, and underlying etiology is often uncertain.
Two Cases of Strictures after Percutaneous CT-Guided Radiofrequency Ablation for Renal Cell Carcinoma
Percutaneous radiofrequency ablation is a safe and effective minimally invasive treatment option in selected patients with T1a tumors of the kidney with a low complication rate. We describe two cases that developed the rare but severe complication of thermal injury-induced strictures of the upper urinary tract and its consecutive management.
Metastatic Thyroid Cancer Presenting as Renal Cortical Mass
The authors present a rare case of primary diagnosis of metastatic, differentiated thyroid cancer presenting as a solitary, large renal mass. Renal cortical masses which represent metastatic primary malignancies are often small, multifocal, and in the setting of active malignancy. Surgical excision of this patient’s renal mass demonstrated the unexpected diagnosis and subsequent endocrine surgical intervention.
Isolated Fungal Balls in Urinary Bladder Presenting as Acute Retention of Urine
A 52-year-old male presented to surgery emergency with acute retention of urine. Patient was relieved in the emergency setting by catheterization and bladder irrigation. Urine was sterile; however, microscopy revealed field full of RBCs (>50/high-power field) and pus cells (>20/hpf). Cystoscopy revealed fungal balls in the urinary bladder which upon histopathological examination showed Aspergillus species. Patient was managed with systemic voriconazole and bladder wash with diluted povidone iodine. Predisposing factors diabetes mellitus and benign prostatic hyperplasia were medically managed, and patient recovered well. This case stresses the importance of considering isolated fungal urinary infections in predisposed individuals.
Bilateral Renal Colic as an Initial Presentation of Erdheim-Chester Disease
Erdheim-Chester disease (ECD) is a rare non-Langerhans cells histiocytosis characterized by multiorgan involvement, with renal-ECD documented in over one-third of patients. Renal disease is generally asymptomatic, rarely causing hydronephrosis and kidney impairment. In addition, the diverse clinical picture of Erdheim-Chester disease arises slowly with sequential manifestations. We present a rare case of a 75-year-old woman on long-term treatment for panhypopituitarism and steroid therapy for vasculitis, presenting to the emergency department with bilateral renal colic and acute kidney injury. Abdominopelvic CT scan revealed renal infiltration with signs of retroperitoneal fibrosis and hydronephrosis. Kidney CT-guided biopsy and 18-fluorodeoxyglucose (FDG) positron emission tomography whole body scan as well as the history of hypopituitarism and vasculitis confirmed the diagnosis of Erdheim-Chester disease. Proper therapy with interferon-α was started. This case describes the multifaced manifestation of this disease and the difficulty to establish the diagnosis, as well as the pivotal role that a urologist can play in its management.
