Rare Primary Fallopian Tube Grade 2 Neuroendocrine Tumor: A Case Report With Review of Literature.

Abstract

Neuroendocrine neoplasms commonly arise from the gastrointestinal tract and lungs. Less commonly, they may occur in the gynecologic tract, typically within the ovary of a mature cystic teratoma. Primary neuroendocrine neoplasms of the fallopian tube are exceptionally rare and only a total of 11 cases have been reported in the literature. We describe the first case to our knowledge of a primary grade 2 neuroendocrine tumor of the fallopian tube in a 47-yr-old female. In this report, we describe the case's unique presentation, review the published literature on primary neuroendocrine neoplasms of the fallopian tube, discuss the treatment options, and speculate on their origin and histogenesis.
