Malignant Mixed Mesodermal Tumor of Ovary in Young Female: A Rare Case Report

Abstract

Carcinosarcoma, also known as malignant mixed mesodermal tumor (MMMT), occurs predominantly in postmenopausal women
of low parity these are very rare neoplasms associated with an aggressive clinical course and overall poor prognosis, stage
is best predictor, and most patients present at advanced stage. Uterus and ovary are common sites for MMMT, though it can
occur anywhere along the female genital tract and in the peritoneum. Microscopically, carcinosarcoma is a biphasic neoplasm
with intermixed epithelial and mesenchymal elements. The sarcomatous component can be homologous or heterologous
depending on whether it is composed of native mesenchymal elements of the organ it arises from or other non-native elements
such as rhabdmyoblastic, osteogenic, chondroblastic or lipoblastic element. The epithelial component can be endometrioid,
undifferentiated, clear cell, or serous. We report a case of MMMT in 22-year-old parous women who present to a gynecologic
department with the complaints of the abdominal mass, pain, vaginal bleeding. Histopathological examination confi rms the
diagnosis of MMMT.
