title: Angiomyomatous Leiomyoma of a Female Urethral Meatus Recurrence After Seven Years of the Resection: A Case Report.
abstract: A 20 years old woman had an external urethral orifice mass and received an excision operation. Seven years later, she complained a tumor with pain that was similar to the previous tumor. She underwent the tumor removal. Pathological diagnosis was a urethral angiomyomatous leiomyoma in the new concept of estrogen receptor-positive smooth muscle tumors.
