Métastase caverneuse d’une tumeur de vessie

The incidence of cavernous metastases after radical treatment for bladder tumor is exceptional and is approximately 1%. The mean time between surgery and the occurrence of metastases is 8 months. In some cases they occur after 10 years. Diagnosis is confirmed by biopsy, which shows their urothelial origin. Here we report the case of 56-year old patient, with a history of smoking, having undergone total cystoprostatectomy in January 2017, who presented 2 months later with induratio penis plastica with no other sign associated. Priapism and gangrene of the penis of infectious origin have been suspected but, given the patient's clinical condition, the more likely diagnosis was cavernous metastasis. On two occasions the patient refused biopsy: during two consultations at 15 days interval (A, B). The patient accepted to undergo biopsy during the 3 consultation (C, D). Biopsy confirmed the diagnosis of cavernous metastasis.
