Histological and immunohistochemical analysis of apocrine breast carcinoma

Abstract
There are few data regarding the biological characteristics of apocrine breast carcinoma in the literature due to its rarity and controversy over its definition. We analyzed the histopathological characteristics and tumor biology of apocrine breast carcinomas with regard to histological grade, p53, HER2, bcl-2, MIB-1 and hormone receptor status.
