Innovative technique for managing extreme relapsing bilateral pseudoangiomatous stromal hyperplasia (PASH) in a young woman: A case report highlighting a novel intervention in reconstruction

Pseudoangiomatous stromal hyperplasia (PASH) is a rare breast stromal lesion that typically manifests clinically as a palpable unilateral, painless lump that is freely movable and has a rubbery or firm consistency. The diagnosis can be confirmed by a core needle biopsy (CNB) or surgical excision. Treatment options include medical treatment with hormonal management for asymptomatic patients or local excision and breast reduction in rare cases.
