Primary peritoneal malignant mixed mesodermal tumor (MMMT) is rare. Surgical removal offers the best treatment, with one patient remaining disease-free for 15 months without chemotherapy.

Area of Science:

Oncology
Gynecologic Oncology

Background:

Malignant mixed mesodermal tumor (MMMT), also known as carcinosarcoma, is a rare and aggressive neoplasm.
While typically found in the uterus or ovary, extragenital MMMT, including primary peritoneal MMMT, is exceptionally rare.

Purpose of the Study:

To report a rare case of primary peritoneal malignant mixed mesodermal tumor.
To discuss the management and treatment of this aggressive extragenital neoplasm.

Main Methods:

Case presentation of a 70-year-old female with a 6-month history of nausea and abdominal discomfort.
Diagnosis of an abdominal mass.
Surgical removal of the tumor.

Main Results:

The patient underwent surgical excision for a primary peritoneal malignant mixed mesodermal tumor.

Keywords:

The patient is alive with no evidence of disease at 15-month follow-up.

No chemotherapy was administered post-surgery.

Conclusions:

Peritoneal carcinosarcomas most commonly arise from the pelvic peritoneum.
Complete surgical cytoreduction is the most effective treatment strategy.
Limited data exists for peritoneal MMMT management, with treatment recommendations based on individual case reports.
