[Metastatic penile lesions secondary to transitional cell carcinoma of the bladder: a rare cause of "malignant priapism"].

Metastases to the penis from transitional cell carcinoma of the bladder are rare. In the literature about 300 cases of secondary penile malignancies were described; 35% out of these cases were from primary neoplasms of the bladder. The Authors describe a case of priapism secondary to penile metastases from a transitional cell carcinoma of the bladder.
