Primary malignant mixed mullerian tumor of the peritoneum: a case report

Haidi Chen, Peipei Hu, Fusheng Wu


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.
