Bilateral Diffuse Pseudoangiomatous Stromal Hyperplasia Necessitating Mastectomy.

Journal Article (Journal Article)

Pseudoangiomatous stromal hyperplasia (PASH) is an uncommon, benign breast lesion often diagnosed incidentally and frequently mistaken for fibroadenoma given similar radiographic appearance. Histopathology classically reveals diffuse, dense fibrous stromal background with a complex network of spindle cells forming slit-like spaces, giving it the appearance of angiomatous proliferation. Surgical excision is generally not necessary. Here we present two unusual cases of PASH: an adolescent patient with bilateral rapid onset of symptoms, and a premenopausal patient with bilateral, diffuse, recurrent PASH. Both required mastectomy. We aim to highlight the variable nature of presentation and briefly review current management options.
