Primary fallopian tube carcinoma (PFTC) is an uncommon gynecologic tumor, responsible for 0.14% to 1.8% of genital malignancies, with a mean incidence of 3.6 per million women per annum. The factors that contribute to its appearance are not well-known. Overall survival percentages for patients with PFTC are generally low. Although the preoperative diagnosis rarely occurs and it is usually first confirmed by the pathologist, an earlier diagnosis occurs with early clinical manifestation and prompt investigation leading to better prognosis. Both PFTC and epithelial ovarian cancer (EOC) are treated with similar surgical and chemotherapy methods. The authors report a case of a patient with bilateral high grade serous carcinoma of the fallopian tube, whose initial presentation was bilateral cystic adnexal masses and serosanguinous discharge, with no other pelvic involvement. This article also reviews in brief and presents updates of this rare gynecological malignancy.
