Case report of a 50 year old lady presenting with leiomyosarcoma after hysterectomy. This is a case of leiomyosarcoma occurring after a hysterectomy done for benign fibroids occurring after 3 years of the surgery. The rarity of this case is due to rare diagnosis of uterine smooth muscle tumour of uncertain malignant potential (STUMP) in patients and incidence of leiomyosarcoma in these cases.
