Figure 2 Pathology. A: Low power magnification [haematoxylin and eosin (HE) staining, 12.5 ×]: Mass including invasive ductal carcinoma and ductal carcinoma in situ inside was encapsulated by delicate fibrous tissue; B: Low power magnification (HE staining, 12.5 ×): Invasive ductal carcinoma and ductal carcinoma in situ involved normal breast tissue external to hamartoma; C: High power field of invasive ductal carcinoma lesion of Figure 2A (HE staining, 100 ×); D: High power field of ductal carcinoma in situ lesion of Figure 2A (HE staining, 100 ×); E: High power field of invasive ductal carcinoma lesion of Figure 2B (HE staining, 200 ×); F: High power field of ductal carcinoma in situ lesion of Figure 2B (HE staining, 200 ×).
