Sclerosing Lobular Hyperplasia-Correlation between Cytomorphological and Histological Findings

Abstract

Sclerosing lobular hyperplasia of the mammary gland is an uncommmon benign lesion which is mainly seen in adolescents and young women. The breast lobules are enlarged due to ductal and acinar proliferations but they have normal architecture. There is extensive fibrosis of the intralobular stroma, and to a lesser degree, of the interlobular parenchyma. Patients generally complain of a palpable, painless/slightly tender and well-defined lump in breast. Fine-needle aspiration cytology of sclerosing lobular hyperplasia is non diagnostic with features similar to fibroadneoma except for the absence of stromal fragments. In order to reach a definitive diagnosis, a histopathologic evaluation is needed. However, a distinction between the two benign entities is of no clinical significance.We are describing a case of sclerosing lobular hyperplasia that occurred in the left breast of a 26-year-old lady.
