Abstract
- Leiomyosarcoma of the bladder is a very rare tumor and it has been reported in less than 200 cases in the literature which represent 0.1% of all nonurothelial bladder tumors. We experienced a case of sarcoma of bladder that protruding into the urinary bladder in 51-year-old woman. She underwent mass excision with enucleation for the bladder function preservation. Pathologically, the mass consisted of high grade leiomyosarcoma. In immunohistochemical study, tumor showed positive reactions for smooth muscle actin and desmin. After mass excision, follow-up radiation treatment is ongoing. Herein, we present the case of a high-grade leiomyosarcoma with literature review.
