This is the case of an advanced stage carcinosarcoma uteri, in a patient with limited therapy options. Carcinosarcomas (malignant mixed Mullerian tumors) are histologically composed of malignant epithelial and mesenchymal components. Sarcomatous component of this mixed tumor in the present patient was of heterologous-type chondrosarcoma. The primary treatment option for uterine carcinosarcomas is surgery, but adjuvant therapy is always necessary. The optimal treatment is still uncertain, as the histogenesis of this tumor remains controversial.
