Carcinosarcoma and mixed müllerian tumors of the fallopian tube: report of four cases.

We report a 74-year-old woman with malignant mixed müllerian tumor and three women, aged 47, 58, and 76 years, with carcinosarcomas, all primary in the fallopian tube. The tumors grew predominantly intraluminally and were associated with hydrosalpinx. All four patients underwent salpingectomy. Two of them received radiation therapy; one died within 9 months because of the tumor and the second is well 2 years after diagnosis. Of the two women without additional therapy, one is alive with tumor 53 months postoperatively and the other is well 1 year after surgery. Available data suggest that these neoplasms are relatively radioresistant and that their prognosis correlates best with local invasiveness.
