Bloody discharge from the breast is most commonly associated with which benign ductal lesion?

• A. Intraductal papilloma
• B. Fibroadenoma
• C. Fat necrosis
• D. Hyperprolactinemia

Answer: (A)

Bloody discharge points to a lesion within a breast duct, and the classic benign ductal lesion that causes this is an intraductal papilloma. This is a benign papillary growth inside a milk duct that has a fibrovascular core. The delicate vessels within the papilla can bleed into the duct, producing spontaneous, unilateral, often blood-tinged discharge that may come from a single duct near the areola. This presentation is typical in premenopausal women and is distinct from other benign conditions. In contrast, a fibroadenoma is a solid lump that typically presents as a painless, well-circumscribed mass rather than discharge. Fat necrosis can cause a lump and skin changes but not usually bloody nipple discharge. Hyperprolactinemia causes galactorrhea, which is typically bilateral, milky, and not related to a focal intraductal process.
