Primary fallopian tube carcinoma is an uncommon malignancy that accounts for 0.14% to 1.8% of gynecological cancers. The clinical symptom is not specific and preoperative diagnosis is easy to miss or delay because of a lack of specific symptoms. We reported a case of bilateral adenocarcinoma of the Fallopian tubes, was occurred in a 51-year-old postmenopausal woman and diagnosed with bilateral salpingectomy for suspicious of suppurative salpingitis. The diagnosis is not always suspected preoperatively. They are assimilated to salpingitis in the early stage, or to ovarian tumors in the advanced stage. The diagnosis is made postoperatively, after an anatomopathological examination. Its etiology is still poorly understood.
