RESUMO
The malignant mixed mullerian tumours [MMMT] or carcinosarcoma of the uterus are rare tumours, they represent 1,4% of all uterine neoplasia. They are characterized historically by double components carcinomatous and sarcomatous. We performed a retrospective study about 25 cases of carcinosarcoma of the endometrium, collected in Salah Azaiz Institute over a period of 30 years going from 1970 to 2000. The mean patient age was 60 years, and 68% of patients were menopaused. The metrorrhagia was revealing in 66% of cases. Clinically, an abdominopelvic mass was found in 12% of the cases. The pathological diagnosis was done in 12 endometrial biopsies and 10 biopsies of the tumour exteriorisated by the cervix. Surgery is the mainstay of the treatment. The prognosis remains dismal
