Abstract

Malignant mixed mullerian tumor (MMMT) occurs rarely extragenital sites and generally originates from female genital tracts such as the uterus. Here, we report a patient with a primary MMMT of the peritoneum in a 64-year-old woman, who experienced a discontinuous epigastric pain and an abdominal distention for 3 months. An ultrasound-guided fine needle aspiration biopsy (FNA) was executed and indicated a highly malignant soft tissue sarcoma. And after that, the patient received a tumor resection (cytoreductive surgery) and postoperative chemotherapy. The postoperative immunohistochemical analysis revealed a MMMT in peritoneum. Up to now, the patient has survived for 5 months.
