Unilateral breast enlargement 5 years after reduction mammaplasty.

A 26-year-old woman presented with unilateral breast enlargement 5 years after bilateral reduction mammaplasty. After careful physical examination combined with a clinical assessment, mammogram, and histologic tissue examination, the patient underwent bilateral reduction mammaplasty using an inferior wedge resection technique. Histologic examination confirmed the diagnosis of a fibrocystic breast disease in both breasts. The most common differential diagnoses are juvenile fibroadenoma, virginal hypertrophy, fibrocystic disease, and cystosarcoma phylloides.
