[Radial scars (scarring) and obliterating mastopathy (author's transl)]

Abstract

The lesion, known under several names, consists of an hyalinized sclerotic center containing abundant elastic and elastoid masses. These radiate into the periphery and enclose lobuli which reveal epithelial proliferation varying from simple hyperplasia with epithelial villi to the rather rare true papillomas. The hyaline and elastic masses in the central parts surround tubuli and correspond to a lesion known as obliterating mastitis (mastopathy) that may lead to total occlusion of the ducts. The entire process ends with a contracting scar that alters the lobuli stemming from the obliterated duct. These may atrophy, dilate, or respond with different forms of hyperplasia. Therefore the designation "radial scars (scarring) possibly with epithelial proliferation" is proposed. As is emphasized the condition may be associated with tubular carcinoma and may resemble pseudoinfiltration in sclerosing adenosis.
