In this study, 3 cases contained pseudoangiomatous stromal hyperplasia (12.5%), and two cases (8.3%) were found to have both sclerosing adenosis

Some of these entities include radial scar, sclerosing adenosis
, fibroadenoma, fat necrosis, and pseudoangiomatous stromal hyperplasia.
The areas of abnormal enhancement had been sampled in 2011, and at that time, pathology results had revealed sclerosing adenosis

is a benign condition of the breast in which extra tissue develops within the breast lobules.
AIDH and IDH are asymptomatic lesions that are detected incidentally on mammography or in the resection specimens of other lesions (fibrocystic change, sclerosing adenosis
, fibroadenoma etc.) .
(5) Diagnostic results can be false positive due to misinterpretation of lobular cancerization and sclerosing adenosis
. False negative results can be due to masking of the foci of disease by inflammatory cells or falsely identifying tumor cells as histiocytes.
Furthermore, FISH analysis is only as good as the cells that are analyzed, and identifying the invasive tumor cells can be challenging, given the presence of confounding elements (e.g., ductal carcinoma in situ, sclerosing adenosis
), tumor heterogeneity, and the fact that FISH is performed in a dark room under ultraviolet light.
Microscopically there was a non-encapsulated lesion with a combination of stroma and cells in the terminal duct lobular units and there was superimposed sclerosing adenosis
indicative of a hamartoma.
Some of these calcifications may be the result of radiation-induced sclerosing adenosis
, a benign process in which fibrotic changes compress glandular tissue causing multiple calcifications.
Histopathologic criteria for JP are as follows: duct papillomatosis, apocrine and non-apocrine cysts, papillary apocrine hyperplasia, sclerosing adenosis
, and duct stasis.
