A 68-year-old man presented with priapism and penile gangrene. The patient had no history of penis trauma or medications for erectile dysfunction. Corpus cavernosa aspiration cytology were positive for malignant cells. Total penectomy was performed. Enhanced chest and abdominal computed tomography showed a left renal tumor with pulmonary and hepatic metastases. Ultrasound-guided renal biopsy showed clear cell renal cell carcinoma.
Priapism is currently defi ned as a prolonged painful erection without sexual stimuli, if priapism persists > 36 hours, conservative treatment does not lead to detumescence. The most common etiologies are: medications into corpora cavernosa, anti-psychotics, anti-hypertensives, hematological disorders (chronic myeloid leukemia). The Penile prosthesis is the choice treatment for restoring the erectile function after the failure of the conservative treatment. But the corporal fi brosis makes it very diffi cult, with high risk of complications [1].
