Radial scars (RS) are radiographic and pathologically benign lesions of the breast that have been previously described in the literature under several different names, such as radial sclerosing lesion, scleroelastotic lesion, indurative mastopathy, nonencapsulated sclerosing lesion, sclerosing papillary proliferation, and, if larger than 1.
Management of radial sclerosing lesions of the breast diagnosed using percutaneous vacuum assisted core needle biopsy: recommendations for excision based on seven years' of experience at a single institution.
Known by names such as elastosis, sclerosing papillary proliferation, radial sclerosing lesion
and sclerosing duct hyperplasia, the radial scar is one of few benign lesions that closely imitates breast carcinoma's ability to form spiculations (small, needle-shaped bodies).
Some synonyms include radial scar, radial sclerosing lesion
, and indurative mastopathy.
Another benign papillary lesion is radial sclerosing lesion
or radial scar.
Histologic sections from the left breast wire-localization biopsy contained a radial sclerosing lesion
in a background of extensive proliferative, fibrocystic changes and a focus of low nuclear grade ductal carcinoma in situ (Figure 1, a and b).
Immunohistochemical detection of maspin is a useful adjunct in distinguishing radial sclerosing lesion
from tubular carcinoma of the breast.
