Malignant mixed Müllerian tumor with heterologous component arising in the fallopian tube--a case report.

Primary malignant mixed Müllerian tumors (MMMTs) of the fallopian tube are rarities in gynecologic oncology with only 26 cases of MMMTs with a heterologous component reported thus far. We report a case of FIGO Stage II primary MMMT of the fallopian tube with a heterologous tumor portion in an 80-year-old woman presenting with abdominal discomfort at the time of primary diagnosis. After performance of total abdominal hysterectomy, bilateral salpingo-oophorectomy and omentectomy follow-up examination three months postoperatively did not show signs of disease recurrence. The patient finally presented six months after the initial diagnosis with extensive intraabdominal metastasis and died several days thereafter. The present report supports the aggressive nature of these neoplasms. The efficacy of chemotherapy and radiation remains to be defined in future studies.
