The thirteenth case of malignant mixed müllcrian tumor of the fallopian tube is reported. These tumors occur predominantly in post-menopausal women. Mean age of the patients at the time of operation was 52 years, and mean survival after diagnosis was 7 months. The longest survival was 15 months. Comparison with clinical data on mixed müllerian tumors of the endometrial cavity reveals that for both sites the behavior and fatal outcome of the neoplasm is the same. The histogenesis of mixed müllerian tumors of the fallopian tube is controversial. Available information suggests that the tumor arises in the tubal stroma rather than in foci of endometriosis.
