Abstract

Adenosarcoma of the uterus is a rare uterine tumour that usually begins in the uterine lining (endometrium). This type of tumour contains both benign (noncancerous) and malignant elements (low-grade sarcoma). Affected individuals may experience abnormal vaginal bleeding, an enlarged uterus, and tissue protruding from the external os (external opening of the uterus that leads into the cavity of the cervix). It most commonly affects postmenopausal women, but it can affect women of any age. Hyperestrogenemia (high blood oestrogen levels), chemotherapy, or radiotherapy are all risk factors for the condition.
