PSEUDOANGIOMATOUS STROMAL HYPERPLASIA (PASH) OF THE BREAST IN AN ADOLESCENT: A CASE REPORT AND LITERATURE REVIEW

Abstract

Pseudoangiomatous stromal hyperplasia (PASH) is a benign proliferative lesion of the breast stroma characterized by slit-like pseudovascular spaces lined by endothelial-like spindle cells. It is frequently found as incidental microscopic foci in the female breast and in gynecomastia of the male breast, but it rarely presents as a clinical problem. We report a case of bilateral extreme breast enlargement caused by PASH in an adolescent girl who was treated with subcutaneous mastectomy and reconstruction with breast implants following a recurrence after treatment with free nipple graft breast reduction.
