In our series of male BC, the least frequent histologic type is the lobular histotype accounting for 4.1% of all tumors (vs. 10% in females), and the most frequent IHC subtype is luminal, whereas basal-like and HER2+ BC are less represented (0% and 10%, respectively) in agreement with Johansson et al. and a SEER database analysis published in 2012 and other studies [9,29,30]. This evidence concerns the gene ERBB2 and breast cancer.
