Primary Fallopian Tube Carcinoma Preoperatively Diagnosed as Cervical Cancer

Abstract

Primary fallopian tube carcinoma (PFTC) is an uncommon gynecologic malignancy that is often diagnosed in the advanced stage. We present herein a case of a 59-year-old female with PFTC diagnosed with an approximately 20-mm cervical tumor on visual inspection. Cervical biopsy showed carcinoma and systemic computed tomography demonstrated no evidence of metastasis. The patient was accordingly diagnosed with cervical adenocarcinoma stage IB1 (FIGO 2008). Abdominal radical hysterectomy including bilateral salpingo-oophorectomy and pelvic lymphadenectomy was performed. However, it was difficult to operate because of dense pelvic organ adhesions and pouch of Douglas obliteration accompanied with deep infiltrating endometriosis. There was no peritoneal dissemination. On histopathological examination, high-grade serous carcinomas arising from the left fallopian tube and metastasized to the endometrium, cervix, vagina and multiple pelvic lymph nodes and forming a tumor in the cervix were noted. The patient was diagnosed with PFTC stage IIIA1 (ii) (FIGO 2014), pT2aN1bM0 (eighth UICC). She received six cycles of docetaxel and carboplatin every 3 weeks and presented no evidence of disease for 6 months after the chemotherapy. In conclusion, this is a rare case in which PFTC was preoperatively diagnosed as cervical cancer. J Clin Gynecol Obstet. 2020;9(1-2):21-24 doi: https://doi.org/10.14740/jcgo630
