Keloid Keloid Keloid, also known as keloid disorder and keloidal scar, is the formation of a type of scar which, depending on its maturity, is composed mainly of either type III (early) or type I (late) collagen. It is a result of an overgrowth of granulation tissue (collagen type 3) at the site of a healed skin injury which is then slowly replaced by collagen type 1. Keloids are firm, rubbery lesions or shiny, fibrous nodules, and can vary from pink to the color of the person's skin or red to dark brown in color. A keloid scar is benign and
Radial scar Radial scar In breast pathology, a radial scar of the breast, formally radial scar of the breast, is a benign breast lesion that can radiologically mimic malignancy, i.e. cancer. Radial scar is associated with atypia and/or malignancy and may be an independent risk factor for the development of carcinoma in either breast. Radial scars are diagnosed by a microscopic examination of excised tissue, i.e. they are diagnosed by pathologists based on their histomorphology. Radial scars are spiculated masses characterized microscopically by a sclerotic appearing (i.e. scar like) center with peripheral entrapped normal breast ducts and lobules. The presence of a
