SAENZ-BATALLA, Gerardo; BOGANTES-LEDESMA, Pilar; LAZO-VALLADARES, Ángel  and  ZUNIGA-BASTOS, Alejandra. A Nodular and Fast Growing Breast Mass. Acta méd. costarric [online]. 2008, vol.50, n.3, pp.177-179. ISSN 0001-6002.

Pseudoangiomatous stromal hyperplasia of the breast is a rare benign disease, which was described by Vuitch in 1986. The etiology is not clear, but an hormonal influence has been demonstrated. To confirm the diagnosis, a biopsy is required primarily to distinguish a malignant disease like low grade angyosarcoma, a fibroadenoma or a Philloides tumor; these entities are similar in their clinical and imaging features. We present herein the case of a 40 year old female that presented with a fast growing, painful, recurrent breast mass, initially treated as fibrocystic breast disease but the histopathology later demonstrated the lesion to be a pseudoangiomatous stromal hyperplasia, which is very infrequent. Finally she underwent a sucutaneuos mastectomy, and the diagnosis was again confirmed. An extensive review of current literature confirmed that mastectomy is better, especially in cases with diffuse and recurrent tumors.

Keywords : Pseudoangiomatous stromal hyperplasia; ginecomastia; philloides tumor; benign fibroquistic breast changes.
