Leiomyosarcoma of the uterus is a relatively rare tumor, representing not more than 2 per cent of uterine leiomyomas.1 [Miller and Rogers,2 in a study made at the Massachusetts General Hospital covering fifty years (1876-1926), found an incidence of 1.4 per cent.] They also described a case in which metastasis to the hip caused spontaneous fracture. Metastasis from leiomyosarcoma is even more rare than the primary tumor.
