Abstract

Pseudoangiomatous stromal hyperplasia(PASH) was initially described by Vuitch et al. as a benign breast lesion, consisting of mammary stromal proliferations which simulate vascular lesions, and which might be mistaken for a low-grade angiosarcoma. This condition occasionally presents as a palpable mass in postmenopausal women, but is more frequently encountered as an incidental component in premenopausal women. Clinical, radiological, and fine-needle aspiration(FNA) findings associated with this condition can mimic those observed in conjunction with a phyllodes tumor or a fibroadenoma. The cytological features of PASH are generally nonspecific, and its diagnosis by FNA cytology is fairly difficult. In this study, we report a case of PASH, manifesting as a palpable mass
