Malignant Mixed Mullerian Tumor of the Uterus– A Complication of Tamoxifen Therapy for Breast Carcinoma

Abstract

Patients with breast cancer exhibit an increased risk in developing neoplasms of other organs. In case of endometrium, the increased risk might be due to tamoxifen adjuvant therapy and prior radiotherapy. Carcinosarcomas are rare uterine cancers and carry poor prognosis. We present a case of Malignant Mixed Mullerian Tumor (MMMT) of the uterus in a 46-year-old woman, after tamoxifen treatment and radiotherapy for breast cancer. We emphasise that postmenopausal women taking tamoxifen should be monitored closely for symptoms of endometrial lesions.
