[Primary neuroendocrine tumor of the fallopian tube: a case report].

Primary neuroendocrine carcinoma arises mainly in the gastrointestinal tract, lungs and pancreas, localization in the fallopian tube is exceptional with only one case being reported in literature. This second case concerns a 54-year-old patient, diagnosed at the Pierre-Zobda-Quitman hospital. Tumor histology revealed a poorly differentiated carcinoma with medium to large cells, marked atypia and high mitotic activity. Immunostaining was positive for chromogranine A, synaptophysine and CD56. Primary fallopian tube neuroendocrine carcinoma requires cross referencing of the radiological, pathological and immunohistochemical findings and discarding the differential diagnoses.
