[Fibroepithelial polyp of the anterior urethra, found during post-operative follow-up of ureteral cancer].

A 52-year-old man underwent nephroureterectomy against left distal ureteral cancer (transitional cell carcinoma, Grade 2, pTa), and was followed up by surveillance alone. Twenty-two months postoperatively, a pedunculated tumor was found in the anterior urethra by cystourethroscopy. Pathological examination of the tumor resected transurethrally revealed a fibroepithelial polyp. There have been only twelve cases of fibroepithelial polyp of the anterior urethra reported in the literature. Since 4 out of 8 adult cases among them were found during the postoperative follow up period of urothelial cancer, mechanical irritation by repeated transurethral procedures might be responsible for the development of fibroepithelial polyp of the anterior urethra in these cases. If anterior urethral tumor is found during follow-up urothelial carcinoma, benign urethral polyp should be considered in the differential diagnosis.
