Introduction The histological types of urethral cancer are mainly squamous cell or transitional cell carcinoma. Neuroendocrine tumor is extremely a rare type of urethral cancer. Case presentation A 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. Conclusion Small cell neuroendocrine tumor could occur on urethral remnant after radical cystectomy with urethrectomy for urothelial cancer. Inspection of the penis and urethral meatus is important during regular follow‐up of patients after radical cystectomy.
