CD31, Also called pseudoangiomatous hyperplasia of mammary stroma, PASH is an incidental microscopic finding in up to 23% of breast surgical resections (, Almost always women who are premenopausal, Myofibroblastic origin, postulated role of hormonal factors (, Usually asymptomatic and an incidental finding but may be detected by imaging (, Histologic examination of resected tissue, May produce a mammographically detected mass, Nonneoplastic but mass forming lesion may rarely recur, especially in younger patients, 11 year old girl with bilateral nodular lesions (, 12 year old girl with pseudoangiomatous stromal hyperplasia (, 30 year old woman with pseudoangiomatous stromal hyperplasia of the breast with foci of morphologic malignancy (, 37 year old woman with giant nodular pseudoangiomatous stromal hyperplasia of the breast presenting as a rapidly growing tumor (, 46 year old woman with bilateral marked breast enlargement (, 67 year old man with pseudoangiomatous stromal hyperplasia of breast (, Local excision needed only in symptomatic mass forming lesions, If diagnosed on core needle biopsy, no surgical excision required, provided the diagnosis is concordant with radiologic findings (, Usually unilateral, well circumscribed, smooth nodule, Cut surface is firm, gray-white, lacks the characteristic slit-like spaces of fibroadenoma, Spaces are usually empty but may contain rare erythrocytes, Cellular areas or plump spindle cells may obscure pseudoangiomatous structure, No mitotic figures, no necrosis, no atypia, Fascicular PASH: cellular variant, in which myofibroblasts aggregate into fascicles with reduced or absent clefting, resembles myofibroblastoma, Moderately cellular with cohesive clusters of bland ductal cells (occasionally with staghorn pattern), single naked nuclei, some spindle cells with moderate cytoplasm and fine chromatin, Occasional loose hypocellular stromal tissue fragments containing spindle cells and paired elongated nuclei in fibrillary matrix (, Findings can confirm benign nature of disease but are nonspecific, resembling fibroadenoma or phyllodes tumor (, Finding plump spindled mesenchymal cells is suggestive (, Spaces are not true vascular channels but due to disruption and separation of stromal collagen fibers.

Conventional fibroadenomas (FAs) are underpinned by recurrent MED12 mutations in the stromal components of the lesions. The sections show a lesion with a pale mildly cellular stroma, and bland glandular elements. (Sep 2005). The purpose of this study is to examine the breast cancer risk overall among women with simple fibroadenoma or complex fibroadenoma and to examine the association of complex fibroadenoma with breast cancer through stratification of other breast cancer risks. Although malignant transformation in FA is rare, there is evidence of an association with breast carcinoma, particularly in middle-aged females with associated risk factors, such as a strong family history and/or BRCA-1/2 mutations. There are no clear cut mammographic or sonographic features that distinguish complex from simple fibroadenomas. Musio F, Mozingo D, Otchy DP.
