title: Urethral recurrence of an urachal carcinoma: a case report.
abstract: A 68-year-old man presented with microscopic hematuria. Cystoscopy revealed a papillary and pedunculated tumor in the bladder dome which, on punch biopsy, proved to be adenocarcinoma. Partial cystectomy and urachal remnant resection were performed. Histopathologically, the tumor was diagnosed as an urachal tumor. Four months after surgery, multiple posterior urethral tumors were found; punch biopsy revealed adenocarcinoma, which was quite similar to the previous tumor. Based on the histopathological examination of the transurethrally resected tissue, the urethral tumor was diagnosed as a recurrence of the urachal carcinoma. No evidence of either tumor recurrence or metastasis was found within the 15 months following the second surgery.
