title: Pseudoangio-matous stromal hyperplasia: A rare tumor of the breast.
abstract: Pseudoangiomatous stromal hyperplasia (PASH) is a benign breast entity described first by Vuitch et al., in 1986. PASH is a benign stromal lesion containing complex anastomosing channels lined by slender spindle cells. It can be mistaken with fibroadenoma on ultrasound examination and histologically with low-grade angiosarcoma and phyllodes tumor. Here, presented is a case report of a 30-year-old female who presented with huge palpable lump in left breast. Ultrasonography revealed the lesion as giant fibroadenoma and fine needle aspiration cytology report was suggestive of cystosarcoma phyllodes. Excision and reduction mammoplasty was done and histopathology report was suggestive of PASH.
