ERBB2 and ductal breast carcinoma in situ: The grade III was the most common as in our series, corresponding to 53% in unclassified subtype, 48% in basal-like, 48% in Her2-overexpressing, 28% in luminal B, 23% in luminal A (p = 0,005), which concord with other studies such as Livasy et al. [15] who demonstrated that the most consistent pathologic features for basal-like subtype including high grade, high mitotic count, geographic necrosis, pushing border, prominent lymphocytic infiltrates, solid growth pattern, central fibrotic/acellular area, and less association with ductal carcinoma in situ.
