Carcinoma of the Fallopian tube is the least frequent tumor of the female genital tract. The diagnosis is difficult but could be made more frequently if the causes of abnormal bleeding were thoroughly investigated by means of cytology and endometrial curettage. Treatment is by resection of the tumor, total hysterectomy, and bilateral salpingo-oophorectomy followed by chemotherapy.

The histological aspect corroborated with the Ki-67 index is strongly suggestive for a choriocarcinoma developed in a tubal ectopic pregnancy.
