Which rare breast lesion presents as a mass often with skin or nipple retraction?

• A. Fat necrosis
• B. Fibroadenoma
• C. Intraductal papilloma
• D. Phyllodes tumor

Answer: (A)

The situation describes a benign process where fat necrosis from prior trauma or breast surgery causes a palpable lump with skin or nipple retraction due to scar tightening. Fat necrosis can imitate cancer because the mass may be irregular and tether the overlying skin, producing dimpling or retraction. Because the fat necrosis reaction can leave oil cysts and calcifications on imaging, clinicians often correlate history of trauma with imaging findings; when uncertainty remains, biopsy helps confirm the benign nature. Fibroadenoma tends to be a smooth, mobile, well-circumscribed lump in younger patients without skin changes. Intraductal papilloma usually presents with nipple discharge rather than a mass with skin retraction. Phyllodes tumor can present as a large, rapidly growing mass and may involve the skin, but its typical presentation and age profile are different, and it’s not characterized primarily by nipple retraction.
