Tumor neuroendócrino primário de mama: Relato de trěs casos e revisáo de literatura

Abstract

Primary neuroendocrine breast carcinomas (NECs) are uncommon. Moreover, there is no consensus as to its treatment and prognosis. In this study, the diagnoses of 1,184 cases of breast cancer treated at Hospital das Clínicas da Faculdade de Medicina de Ribeiráo Preto/Universidade de Sáo Paulo (HCFMRP/USP) were reviewed. Three among them fulflled the criteria for primary NEC according to the classifcation established by the World Health Organization (WHO) in 2003. Clinicopathological, immunohistochemical features and treatments were assessed in order to characterize histopathological and distinct patterns of conventional breast carcinomas.
