Abstract

In 2009, a 53-year-old woman developed a nodule with a central depression on her right thigh at a site she had injured by nail scratching and at which scar formation had subsequently occurred. Dermoscopy revealed a delicate peripheral pigmented network and a central white network. Histopathologically, the reticular dermis of the lesion showed thinning accompanied by the loss of elastic fibers and a focal increase of collagen fibers, and proliferation of fibroblast-like cells that were positive for factor XIIIa. The epidermis showed acanthosis with hyperpigmentation in the basal layer and deeply elongated rete ridges showed folliculo-sebaceous induction with ductal structures. Atrophic dermatofibroma is a specific type of dermatofibroma, and it often has epidermal hyperplasia with adnexal induction.Skin Research, 12: 296-300, 2013
