Tumoral pseudoangiomatous stromal hyperplasia: Radiological and pathological correlation with review of literature

Tumoral pseudoangiomatous stromal hyperplasia (PASH) is rare and presents more often as a clinically apparent, well-circumscribed, solid mass. It may clinically and radiologically mimic fibroadenoma or Phyllodes tumor. In this article, our objective was to describe the clinical presentations, ultrasound and histopathological appearances of tumoral PASH in three patients. Among the three PASH tumors, all except one were palpable breast masses; and the non-palpable mass was detected on ultrasound. All patients underwent core biopsy followed by wide local excision of the mass which were histopathologically proven to be PASH.
