A study of 11 patients. The pictured lesion is sclerosing adenosis, a benign breast lesion characterized by expansion of glands (with preserved 2 cell layers: inner epithelial and outer myoepithelial cells) within the terminal duct lobular unit with distortion by fibrosis / sclerosis.

Findings can confirm benign nature of disease but are nonspecific, resembling fibroadenoma or phyllodes tumor (Indian J Pathol Microbiol 2005;48:260) Finding plump spindled mesenchymal cells is suggestive (Diagn Cytopathol 2005;32:345) Fibroadenoma, abbreviated FA, is a common benign tumour of the breast.

When histopathology on core biopsy reveals a higher-risk lesion, such as atypical lobular hyperplasia, excisional biopsy may be indicated to rule out malignancy.

Int J Environ Res Public Health. Sclerosing adenosis and risk of breast cancer. 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. Giant juvenile fibroadenoma: a systematic review with diagnostic and treatment recommendations. Stroma is generally more sparse than in conventional fibroadenoma.

Although no significant difference was noted in patients' age and tumor size between CFA and NCFA, 5 CFA cases (33.3 %) were accompanied by the presence of carcinoma in the same breast or the contralateral breast while no NCFA cases had carcinoma in the breast.
