On histology, sclerosing adenosis, as the name indicates, comprises lobules expanded by proliferated acini (adenosis) with, in addition, a variable amount of intervening stromal sclerosis that may result in compression and distortion of the acinar structures.
Pathology Outlines Sclerosing adenosis
As a subtype of adenosis, sclerosing adenosis (SA) is a benign proliferative disease of the breast associated with disordered acinar, myoepithelial and connective tissue in the terminal ductal lobular unit.

The first one is sclerosing adenosis, which is the subtype characterized by calcifications and proliferation of small ductules and acini in the lobules. The second one is epithelial hyperplasia of cells in terminal ducts and lobular epithelium, which is associated with an increased risk of breast cancer only if there's a presence of atypical.

Sclerosing adenosis proved to be a minor component at core biopsy for 44 lesions, including one invasive ductal carcinoma, one ductal carcinoma in situ (DCIS), one focus of atypical ductal hyperplasia (ADH), and one atypical lobular hyperplasia.

Sclerosing adenosis is a common lesion of the breast, most prevalent in women of reproductive or perimenopausal age, especially those in the third and fourth decades. It is present in over one quarter of all benign breast biopsies, frequently in association with other proliferative and nonproliferative fibrocystic changes [ 4 ].
Breast carcinoma in sclerosing adenosis a clinicopathological and
Sclerosing adenosis is a special type of adenosis in which the enlarged lobules are distorted by scar-like tissue. This type may cause breast pain. Diagnosis of breast adenosis If many enlarged lobules are close to one another, they may be large enough to be felt as a breast lump.

The pathological and radiological aspects of this benign breast condition have been emphasized since they influence clinical practice. Features of 43 patients diagnosed as having sclerosing adenosis have been.

Epidemiology. Most common benign tumor of the female breast. Most common breast tumor in adolescent and young women. Can occur at any age, median age of 25 years ( J R Coll Surg Edinb 1988;33:16 ) Juvenile fibroadenoma generally occurs in younger and adolescent patients < 20 years; reported in children at a very young age ( Am J Surg Pathol.

Duct ectasia. Columnar alteration with prominent apical snouts and secretions (CAPSS) Papillomatosis. Fibrocystic changes. All of these are benign (non-cancerous) changes that the pathologist might see. These conditions generally do not need to be treated unless they're causing bothersome symptoms.

SA is a lobulocentric proliferation of distorted acini around a central duct with preservation of myoepithelial cells, accompanied with varying degrees of epithelial atrophy and stromal fibrosis. Clinical Features Incidence SA is often an incidental finding in breast tissue removed for other reasons.

Sclerosing adenosis is a benign, usually asymptomatic lobulocentric proliferative process that involves both the epithelial and the mesenchymal component of the breast. It is commonly an incidental finding in perimenopausal women undergoing screening mammography. Case Report

Sclerosing adenosis is a type of adenosis in which enlarged acini become slightly distorted by surrounded stromal fibrosis ("sclerosis"). The normal lobular architecture of the breast is maintained but becomes exaggerated and distorted. Radiographic features Mammography
