Correct Answer � C
Explanation

Answer : C Fat necrosis
-
The condition described in question is fat necrosis.
-
Fat necrosis is typically caused by trauma to the breast. The damaged, necrotic fat is phagocytosed by macrophages, which become lipid laden. The lesion resolves as a collagenous scar within weeks to months.
-
The firm scar can mammographically and grossly resemble a carcinoma, however.
-
A fibroadenoma is a neoplasm, and tumors are not induced by trauma. Sclerosing adenosis is a feature of fibrocystic changes, a common cause of nontraumatic breast lumps.
-
An intraductal carcinoma may not form a palpable mass lesion.
