[Leiomyoma of the bladder]

To present an additional case of leiomyoma of the bladder, a rare tumor that is frequently discovered incidentally, and to review the few cases reported in the Spanish literature, with special reference to the clinical aspects, complementary tests and treatment.

A case of leiomyoma of the bladder in a patient who had come to deliver after a full-term pregnancy is presented. Routine physical examination on admission revealed a tumor in the anterior aspect of the vagina. Ultrasound, radiological and endoscopic studies were performed. The Spanish literature is reviewed with special reference to the clinical aspects, complementary tests and treatment.

After the diagnosis of a bladder tumor had been confirmed and the effects on the adjacent structures determined, TUR biopsy was performed. The anatomopathological analysis demonstrated leiomyoma of the bladder.

The ultrasound and radiological images of leiomyoma localized to the bladder are sufficient to suspect the nature of the lesion, but the definitive diagnosis is based on the anatomopathological findings. The choice of the type of surgery, open or endoscopic, is based on tumor localization and size.
