Abstract:
Malignant melanoma in the urethra is a rare tumor that is difficult to diagnose and treat, leading to a poor prognosis. In this paper, we present the case of a 36-year-old woman with history of invasive rectal adenocarcinoma (PT2N0Mx) who was tumor free for 5 years presented to urology outpatient with history of poor stream, dysuria, and dyspareuria. On examination, there was a huge mass in the meatus of urethra. Urethral malignant melanoma shows a high rate of local recurrence, about 60 % in 1 year. Overall survival in a series of 11 cases at 3 years was 27 %.
