Explain of Neoplasia

32. Infiltrating ductal carcinoma of breast, gross

This infiltrating ductal carcinoma of the breast is definitely infiltrating the surrounding breast. The central white area is very hard and gritty, because the neoplasm is producing a desmoplastic reaction with lots of collagen. This is often called a "scirrhous" appearance. There is also focal dystrophic calcification leading to the gritty areas.
