This report details a rare case of carcinosarcoma of the abdominal wall. A 62–year–old female patient with no prior history of abdominal surgery was referred to our hospital. She experienced general malaise and had a palpable mass of 8 cm at the lower right quadrant of her abdominal cavity since a month prior to admission. Imaging studies revealed invasion of a large tumor into the abdominal wall. The patient was operated to resect the tumor and to determine future treatment possibilities. Operative findings suggested development of a primary lesion from the abdominal wall, and histological findings revealed a carcinosarcoma. The origin of this carcinosarcoma was unclear, and hence, immunohistochemical studies were performed. Based on surgical findings and CD10 positivity, the tumor was diagnosed as primary peritoneal malignant müllerian mixed tumor (MMMT). The patient underwent adjuvant chemotherapy, but succumbed to the disease on postoperative day 34. Previous literatures and the present case suggest that primary peritoneal MMT is rare neoplasm, and it is highly malignant and aggressive with a poor patient prognosis.
