A rare bladder tumour: A case presentation of primary low-grade leiomyosarcoma of the urinary bladder in a female patient

Abstract

Leiomyosarcoma is a mesenchymal tumour and rarely occurs as a primary bladder tumour. It is considered as a rare and aggressive tumour with a poor prognosis. To this date, there is no clear and precise therapeutic approach for the treatment of bladder leiomyosarcoma and little is known about the long term survival. The consensus in the current literature is that surgical intervention is the preferred initial treatment option and that prognosis is mainly determined by tumour differentiation. Organ-sparing surgery might be a feasible therapeutic option in selected patients.
