Invasive ductal carcinoma (I). An 88-year-old woman with a palpable nodule in the lower inner quadrant of her left breast. a Synthesized 2D mammogram shows a spiculated nodule (circle), classified as infiltrating lobular carcinoma at histology. Note the thickening of the skin and of the nipple-areolar complex (arrows). b MRI shows pathologic asymmetric enhancement of the left nipple-areolar complex. c Hematoxylin-eosin stain of punch-biopsy specimen (× 10) shows extensive dermal infiltration by infiltrating ductal carcinoma. d Immunohistochemistry (× 4) shows diffuse nuclear expression of estrogen receptors. These are two synchronous tumors
