Radial Scar

ra·di·al scle·ros·ing le·sion

a variant of sclerosing adenosis of the breast with central scar formation and radiating hyperplastic ducts.

Farlex Partner Medical Dictionary © Farlex 2012
Any of a group of breast lesions which can mimic invasive carcinoma by physical exam, radiology, gross exam and microscopic exam. The lesions are small, stellate by gross and low-power microscopy and characterised by central fibrosis—usually with an elastotic core and varying amounts of epithelial proliferation and distortion. Microcalcifications can be seen

Interestingly, hamartoma was associated with a radial scar in one case.
Proliferative lesions without atypia include ductal hyperplasia of the usual type, sclerosing adenosis, radial scar, and intraductal papilloma.
Radial scar at image-guided needle biopsy: is excision necessary?
(2) Several, non-malignant risk factors have been associated with an underlying occult breast cancer and, as a result, a core biopsy diagnosis of atypical ductal hyperplasia, atypical lobular hyperplasia, radial scar formation, and intraductal papilloma have prompted an excisional biopsy.
Radial scar (RS) is a pseudo-infiltrative lesion characterized by a fibro-elastotic core with entrapped ducts and surrounding radiating ducts and lobules demonstrating a range of epithelial hyperplasia.
Magnetic resonance imaging (MRI) characteristics of this mass include a hyperintense central radial scar on T2 weighted imaging.
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).[10,26] In fact, it can mimic cancer not only mammographically, but also on gross and microscopic examination.[26]
If the tissue has an abnormality called a radial scar, the woman is almost twice as likely to develop cancer.
The characteristics of JP as described earlier such as presence of a large, palpable mass and the patients' age below 30 were in contrast to radial scar - consistent with our case.
Some synonyms include radial scar, radial sclerosing lesion, and indurative mastopathy.
(6) Multiple papillomas may be highly susceptible to malignant transformation, likely due to their slightly different cytologic architecture, and are also associated with a higher risk (3.0) of hyperplasia, atypia, DCIS, sclerosis adenosis, and radial scar. (1,4) Papillomatosis with atypia has a 7.0 higher relative risk of developing breast carcinoma.
The five biopsies with benign results included two fibroadenomas, one radial scar, one fibrous histiocytoma, and one area of fibrosis.
