Malignant Mixed Mullerian Tumor (Carcinosarcoma)
MMMT contains high-grade malignant stromal and epithelial components arranged in a biphasic pattern as seen in this image. The biphasic pattern may be less obvious in some cases. In rare cases, both malignant components are low-grade. The usual patient is a post-menopausal woman, although rarely it may occur in younger women and even in children.
