A case of malignant müllerian mixed tumor of the uterine corpus

Abstract

A case of malignant müllerian mixed tumor (MMMT) of the uterine corpus in a 58-year-old woman is presented. Cytologic examination with endocyte^R revealed the coexistence of epithelial and non-epithelial malignant cells prior to histologic diagnosis. Histologically, the tumor was composed of well-differentiated endometrial type adenocarcinoma and rhabdomyosarcoma, as a heterologous element. She died of the primary tumor 42 months after the initial operation despite two surgeries and intensive chemotherapy.
