Stage I primary malignant mixed müllerian tumor of the fallopian tube. Report of a case with five-year survival after minimal surgery without adjuvant treatment

Abstract

Background: Sarcomas of the fallopian tube are rarities in gynecologic oncology, consisting of < 1% of all genital sarcomas.

Case: A 70-year-old woman with a stage I malignant mixed müllerian tumor (MMMT) (International Federation of Gynecology and Obstetrics classification of fallopian tube carcinomas) did not undergo radical surgery or adjuvant treatment because of the patient's refusal of them. The patient underwent only abdominal hysterectomy with bilateral salpingo-oophorectomy. She was discharged feeling well and without abnormal clinical findings. Sixty months after primary surgery there were no signs of recurrence.

Conclusion: This case suggests the possibility of a good prognosis in early-stage MMMT, especially if there is no deep infiltration of the fallopian tube muscle layer or lymphatic permeation and if the peritoneal cytology is negative. The important feature of this report is the five year disease-free survival after nonradical surgery for prognostically favorable MMMT.
