Immunohistochemical and clinicopathologic characteristics of invasive ductal carcinoma of breast with micropapillary carcinoma component.

Abstract

Based on the frequent nodal metastases and association with higher stage found in IMC as compared with NIMC cases, as well as higher p53 positivity and lower frequency of estrogen receptor expression, MC could be considered an aggressive histologic type of breast carcinoma. In both MC and non-MC components in IMC cases, no basallike immunostaining pattern was detected.
