Bilateral primary papillary serous carcinoma of the fallopian tube – A rare case scenario

Abstract

Bilateral primary fallopian tube carcinoma is a very rare case scenario. Approximately, its incidence is 0.02% of all the gynecological malignancy. A 40-year-old female patient visited the hospital with complaints of lower abdominal pain for 3 months. Ultrasound of the pelvis shows complex bilateral adnexal lesions with ORADS score 4 – intermediate risk. The serum CA-125 is elevated. The provisional diagnosis of bilateral pyosalpinx was made. The uterus with bilateral ovaries and fallopian tubes was removed. On histopathology, thus, the final diagnosis of primary bilateral papillary serous carcinoma of the fallopian tube was made. Bilateral primary fallopian tube carcinoma is a very rare case scenario. Intraoperative frozen study is to be done to diagnose this entity. The high degree of suspicion is required to diagnose a case of bilateral fallopian tube carcinoma as it is a very rare case scenario and usually confused for pyosalpinx.
