Abstract

Background/aim: Pseudoangiomatous stromal hyperplasia (PASH) is a rare and benign mesenchymal proliferative breast lesion. Our aim is to review the clinical and radiological features of PASH and define a standard approach for its diagnosis and management. Materials and methods: Clinical records of 35 consecutive patients with PASH were retrospectively reviewed between 2009 and 2015. Patients with clinically or radiologically detected mass and patients who underwent biopsy for other indications and were diagnosed incidentally were included in the study. Results: There were 34 female patients and one male patient with gynecomastia. Twenty-three patients had palpable masses, and 16 of them were diagnosed as PASH with a median size of 3.1 cm. PASH did not show any specific features in radiological imaging. Core needle biopsy was performed for 3 patients before surgical excision; however, the lesions had not been diagnosed as PASH. In pathological examination, lesions associated with PASH showed nonproliferative changes in 14 patients, proliferative changes without atypia in 17, one phyllodes tumor, one in situ tumor, and one invasive cancer. Conclusion: Imaging findings of PASH are nonspecific. It is difficult to give a true prognostic diagnosis through pathological evaluation of big masses with core needle biopsy. We recommend surgical excision, especially for big lesions with suspicious features.
