title: Malignant priapism secondary to isolated penile metastasis from a renal pelvic carcinoma.
abstract: We report a case of isolated penile metastasis from renal pelvic carcinoma in a 69-year-old man with malignant priapism. The patient had radical resection of the renal pelvic carcinoma 2 months earlier with urothelial carcinoma (UC) and sarcomatoid differentiation histology. Physical examination showed no visible skin lesions, but a palpable hard nodule was present over the penile shaft. The imaging studies did not reveal other metastases. Cavernous-Glans shunt and nodule resection were performed, and histological examination showed metastasis UC with sarcomatoid differentiation. To our knowledge, we describe the first case of malignant priapism due to isolated penile metastasis of renal pelvic carcinoma.
