[Mixed malignant Müllerian tumors of the uterus]

Mixed malignant Müllerian tumours have an epithelial component and a connective tissue component both of which are malignant. The exact nature of each gives rise to a large number of clinical varieties and that has given rise to a confusing nomenclature. All have in common that they occur after the menopause and that they appear to be banal but that their prognosis is awful. The frequency of these tumours seems to be increasing. It is essential to recognise them because their treatment has to be more profound than that carried out for endometrial adenocarcinoma. The initial treatment of the lesions is by surgery and radiotherapy. Chemotherapy is to be reserved to improve the prognosis which itself is linked to the amount of distant metastases.
