Keloidal scleroderma.

Progressive systemic sclerosis (PSS) can involve the skin diffusely or in a limited way. Rarely cutaneous involvement can assume a hypertrophic form, described in the literature as keloidal scleroderma. The authors describe a PSS patient who presented cutaneous manifestations compatible with the diagnosis of this clinical situation. The clinical features, pathogenic mechanism and therapeutic approach are discussed and a broad review of the literature is given.
