Match each clinical presentation with the most likely underlying breast pathology.
- A 21-year-old nulliparous woman presents with a 2-cm, rubbery, highly mobile, non-tender mass in the upper outer quadrant of her left breast.Fibroadenoma
- A 41-year-old woman reports spontaneous, unilateral, bloody nipple discharge. Physical examination reveals no palpable breast masses or axillary lymphadenopathy.Intraductal papilloma
- A 49-year-old perimenopausal woman presents with a soft retroareolar mass, mild nipple inversion, and a thick, pasty, greenish-white nipple discharge.Mammary duct ectasia
- A 36-year-old woman complains of bilateral, diffuse, cord-like breast thickening and pain that begins a week before her period and resolves after menstruation.Fibrocystic changes
Answer
The presentations map directly to hallmark benign conditions: the young woman with a mobile mass has a fibroadenoma, the bloody discharge without a mass is an intraductal papilloma, the green discharge with a retroareolar mass is mammary duct ectasia, and the cyclic premenstrual pain represents fibrocystic changes.
Each diagnosis represents a distinct benign breast condition with classic clinical features. Fibroadenomas present as mobile, well-circumscribed masses in young women. Intraductal papillomas present with bloody nipple discharge but no mass. Mammary duct ectasia causes thick, colored discharge and retroareolar masses due to ductal inflammation. Fibrocystic changes cause diffuse, cyclic breast pain and nodularity linked to the menstrual cycle.
