Mammary pseudoangiomatous stromal hyperplasia – a case report.

Objectives:To describe the clinical, radiologic, cytologic and histologic features of a case of mammary pseudoangiomatous stromal hyperplasia (PASH). Materials and Methods:The authors reviewed the clinical, radiologic, cytologic and histologic results in a case of PASH in 31-year old, nonpregnant woman presented with a painless nodule in left breast.The findings were compared with those in the literature. Results: Clinicaly PASH is indistinguishable from a fibroadenoma. Sonographic findings included ovoid, cirscumscribed, hipoechoic solid mass which is similar to fibroadenoma. Fine needle aspiration cytology was performed under sonographic guidance and the cytologic features were consistent with atypical fibroadenoma. The mass was surgicaly excised. Histologic analyses was performed and a diagnosis of PASH was made. Conclusion: A definitive diagnosis of a PASH is unlikely on the basis of the cytologic examination alone. To confirm the diagnosis of a PASH a biopsy is required. PASH needs to be distinguished from low-grade angiosarcoma and some borderline lesions which often have a similar cytologic appearance. Management of PASH is similar as for fibroadenoma – periodic mammographic and sonographic surveillance or surgical excision.
