Carcinoma neuroendocrino primario de la glándula mamaria, reporte de caso y revisión de la literatura

Primary breast neuroendocrine carcinoma is a rare subtype of breast neuroendocrine tumors. Given the low incidence of this disease, most published articles in the literature are case series, therefore, the results regarding the biologic behaviour and prognosis are divergent. The main characteristic of this group of tumors is the histopathological expression of both epithelial and endocrine immunohistochemical markers to a greater or lesser degree, which in some cases can even coexist in the same cell. Hereby we present the case of a female patient with a breast neuroendocrine carcinoma, with a revision of clinical features and treatment options.
