Sclerosing lobular hyperplasia of the breast after reduction mammaplasty

Sclerosing lobular hyperplasia is a uncommon benign fibroproliferative lesi on of the breast similar to a fibroadenoma, It usually presents as a mass i n the outer quadrant of the breast of younger women. The authors report an atypical case of sclerosing lobular hyperplasia that presented as bilateral breast masses in an elderly woman after a reduction mammaplasty. Breast ma sses that develop after reduction are often a result of fat necrosis, inter nal scarring, or organizing hematomas. Those that do not resolve warrant op en biopsy because they may represent malignant or benign neoplasms.
