Abstract

Primary carcinoma of the fallopian tube is a rare, but fatal gynecologic cancer. The preoperative diagnosis of this carcinoma is chal-lenging due to the absence of specific symptoms and signs, and in most patients, it is an intraoperative finding. A 55-year-old patient (G3Ab1P2) was referred to the urogynecology clinic of our hospital with the chief complaints of heavy, prolonged menstrual bleeding and a persistently abnormal yellow discharge, which could not be distinguished by the patient from urinary leaks. After a com-plete diagnostic work-up, the patient was identified as a candidate for hysterectomy due to abnormal vaginal bleeding resistant to megestrol acetate, family history of malignancy, and abnormal vaginal discharge. Laparotomy revealed unusual left fallopian tube features (large, bulky, and vegetative), suggesting malignancy. The intraoperative frozen-section analysis of the left fallopian tube and the ovarian specimens indicated the mass as a high-grade serous carcinoma of the fallopian tube. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, and partial omentectomy were performed for the patient. The definitive histopathological diagnosis was high-grade serous carcinoma of the left fallopian tube (stage 2b) with omental involvement, without any evidence of lymphovascular invasion. High-grade serous carcinoma of the fallopian tube is likely to have non-specific symptoms, causing a significant delay in diagnosis and treatment, which negatively affects the prognosis and survival of these patients. © 2021, Author(s).
