Neuroendocrine tumor is extremely a rare type of urethral cancer.Case presentationA 72-year-old man visited with an erythema at the external urethral meatus. After 3 months, a 1-cm reddish solid tumor was found on the external urethral meatus. He had a history of bladder cancer (pTa with carcinoma in situ), including the prostatic urethra, and underwent radical cystectomy with urethrectomy and ileal conduit construction 11 years ago. After 3 months, a 1-cm reddish solid tumor was found on the external urethral meatus. The pathological diagnosis was a neuroendocrine tumor. Partial penectomy was performed.ConclusionSmall cell neuroendocrine tumor could occur on urethral remnant after radical cystectomy with urethrectomy for urothelial cancer.
