Glomus Tumor of the Kidney Harboring Malignant Potential.

Glomus tumors are rare, benign, vascular neoplasms arising from the glomus body. Although they occasionally develop in any part of the body, they do so more common in the upper extremities, most frequently subungual areas. An extensive review of the literature revealed less than thirty cases of primary renal glomus tumors. We present a unique case of an adult male with an incidentally discovered 2.5 cm right renal mass. Histopathologic and immunohistochemical examination suggested the diagnosis of glomus tumor. Based on the World Health Organization (WHO) classification of soft tissue tumors, the presence of at least two atypical features indicates malignant potential. In this case, deep/visceral location and size greater than 2 cm fulfilled these criteria. Following an uneventful excision and a 12-month follow-up period, the patient remains disease-free with no sign of local or distant metastases.

Total Osseous Calcification of the Prostate Gland.

Prostatic calculi are commonly seen in older men as their incidence increases with age. They are associated with prostate hypertrophy, chronic inflammation of the gland, prostate cancer, and rarely with other pathological conditions such as granulomatous diseases. Although typical small in size, they can seldom become giant and replace the entire prostate gland with only few cases reported in literature. We present one such rare case of a young male who presented to the emergency department with clinical manifestations of sepsis and no relevant past medical history. The patient was ultimately treated with open simple retropubic prostatectomy as a surgical stone extraction method.

Prostatosymphyseal Fistula After Photoselective Vaporization of the Prostate: A Very Rare Complication of a Transurethral Surgery.

Prostatosymphyseal fistula (PSF) is a very rare complication described after transurethral surgery of the prostate including photoselective vaporization of the prostate (PVP) with GreenLightΤΜ laser (Boston Scientific, Marlborough, MA). Sporadic cases have also been reported in the literature as side effects of pelvic radiation therapy. We present a 65-year-old male patient who underwent PVP as an elective procedure for the treatment of severe lower urinary tract symptoms. The primary management after the diagnosis of the fistula was conservative but as this did not result in an expected improvement, the patient underwent radical prostatectomy as a last resort. PSF formation is the result of the communication between the anterior capsule of the prostate and the bladder neck via pubic symphysis and the surrounding tissues. This condition often leads to either urinoma formation or osteitis pubis. In the majority of cases, treatment options are complex surgical reconstruction using flaps or grafts, radical prostatectomy or urinary diversion as an ultimate solution. The rarity of the complication and the accompanied atypical signs and symptoms warrant a low threshold for suspicion so as to diagnose the event early and provide the appropriate treatment.
