Malignant mixed mullerian tumor of fallopian tube with multiple distinct heterologous components

We experienced a case of primary malignant mixed müllerian tumors (MMMTs) of the fallopian tube of FIGO stage I. In addition to endometrioid adenocarcinomas, multiple apparent heterologous elements encompassing myxoid chondrosarcoma, osteosarcoma, myxoid liposarcoma, and well-differentiated angiosarcoma were recognized separately in each nodule. Those findings that divergent sarcomatoid differentiations are apparently present masquerading malignant mesenchymoma have not been described in MMMTs of the female genital tract.ope
