Leiomyosarcoma of uterus--a case report.

Leiomyosarcoma of uterus is a very rare malignant mesenchymal tumour of uterus. It may arise from the uterine myometrium de novo or may be transformed from a pre-existing benign leiomyoma. A 55-year-old female presenting with 20-22 weeks size of uterus and bleeding per vagina was clinically diagnosed as a case of leiomyoma uteri and cervical polyp, was subjected to abdominal hysterectomy. The tumour mass was later confirmed histologically as leiomyosarcoma of uterus presumed to be transformed from pre-existing leiomyoma uteri.
