Benign neoplasms of the bladder are a rare pathology. Non-epithelial benign tumors of the bladder (fibromas, fibromyxomas, fibromyomas, hemangiomas, rhabdomyomas, leiomyomas, etc.) account for less than 0.5% of all that affect this organ. The analyzed literature describes about 250 cases of bladder leiomyoma. This article describes the clinical case of surgical treatment of bladder leiomyoma.
