On pelvic examination, a red like mass was seen into urethral external meatus. Under local anesthesia, the patient underwent a basic excision of the urethral mass. Histopathological examination confirms the diagnosis of urethral leiomyoma.Clinical discussionUrethral masses are uncommon. The benign of which include urethral caruncle, Skene's duct cyst, Gartner's duct cyst, papilloma, hemangioma, and leiomyoma. After examination of the patient initial diagnosis was caruncle but after the pathology results showed leiomyoma.ConclusionUrethral leiomyoma is a rare benign tumor, which does require a histopathological examination for a definitive diagnosis despite being a benign formation. Urethral leiomyoma can be successfully removed with good outcomes.
