Unusual location of a plexiform neurofibroma in the fallopian tube: A case report

It is rare for neurofibromatosis to occur in the female genital tract. We report a case of a plexiform neurofibroma in the left fallopian tube in a 50-year-old postmenopausal woman. The initial diagnosis was a pedunculated leiomyoma or a fallopian tube tumor. Laparotomy was performed and a solid mass approximately 90 x 60 x 40 mm in size was found in the left fallopian tube. Total abdominal hysterectomy and bilateral salpingo-oophorectomy with an appendectomy, lymphadenectomy and omentectomy was performed. The histopathological diagnosis was plexiform neurofibroma. Although neurofibromatosis may involve various gynecological structures, to the best of our knowledge, localized plexiform neurofibroma in the fallopian tube has not previously been reported. The presented case is the first report of clinical, ultrasound and histopathological findings in a fallopian tube neurofibroma. Neurofibroma is a neoplasm that should be taken into consideration when diagnosing pelvic masses.
