Understanding Your Pathology Report: Benign Breast Conditions National Library of Medicine Breast cancer risk (observed versus expected) across fibroadenoma levels was assessed through standardized incidence ratios (SIRs) by using age- and calendar-stratified incidence rates from the Iowa Surveillance, Epidemiology, and End Results registry.

Background: To determine the cytomorphological features of complex type fibroadenoma (CFA), we reviewed fine needle aspiration (FNA) cytology with correlation to its histopathology findings, and compared them with non-complex type fibroadenoma (NCFA). Silverman JS, Tamsen A. Mammary fibroadenoma and some phyllodes tumour stroma are composed of CD34+ fibroblasts and factor XIIIa+ dendrophages. No cytologic atypia is present. 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.

Over time, a fibroadenoma may grow in size or even shrink and disappear. Patients with complex lesions were 18.5 years older (median age, 47 years; range, 21-69 years) than patients with noncomplex fibroadenomas (median age, 28.5 years; range, 12-86 years) (p < 0.001). Complex fibroadenomas were half the size (average, 1.3 cm; range, 0.5-2.6 cm) of noncomplex fibroadenomas (average, 2.5 cm; range, 0.5-7.5 cm) (p < 0.001).
