Ductal carcinoma in situ
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.
