Leiomyosarcoma (LMS) is an uncommon malignant tumour of smooth
muscle origin. It arises in the gastro-intestinal tract, retroperitoneum,
urinary bladder, uterus and soft tissue. Peritoneal leiomyosarcomatosis
(PL) is defined as a peritoneal dissemination of a primary sarcoma. We
present a case of leiomyosarcomatosis with widespread dissemination
including involvement of both breasts.
