Leiomyosarcoma of the vaginal wall causing difficulty in micturition: a case report

A 52-year-old woman was admitted because of a vaginal-wall tumor adjacent to the external urethral orifice. The tumor had been causing disturbances in micturition for the past year. Magnetic resonance imaging and computed tomography images indicated a 6 x 3 cm solid mass in the anterior vaginal wall. The tumor was enucleated surgically through a median longitudinal incision of the anterior vaginal wall. Micturitional disturbances were rectified after surgery. Histologically, the tumor was a mixture of a high-cellularity area with a mitosis rate of 7 per 30 high-power fields, and a less cellular area without mitosis. Immunohistochemical staining was performed for both areas. The prognostic implications of the tumor are discussed.
