Other hypertrophic and atrophic conditions of skin
Circumscribed scleroderma
- A chronic disorder, possibly autoimmune, marked by excessive production of collagen which results in hardening and thickening of body tissues. Localized scleroderma typically affects the skin, with formation of patches or lines of thick and unyielding tissue; there can be muscle and underlying tissue involvement as well as occasional joint complications. The affected areas of skin can be restrictive and disfiguring. The shape, depth and location of the affected area is used to classify one of the four types of local scleroderma. An individual can have a combination of localized scleroderma types.
Keratoderma acquired
Acquired acanthosis nigricans
- circumscribed melanosis consisting of a brown pigmented, velvety verrucosity or fine papillomatosis appearing in the axillae and other body folds; occurs in association with endocrine disorders, underlying malignancy, administration of certain drugs, or as in inherited disorder.
Striae atrophicae
Keloid scar
- progressively enlarging scar resulting from formation of excessive amounts of collagen in the dermis during connective tissue repair; spreads to surrounding tissues.
- (KEY-loyd) A thick, irregular scar caused by excessive tissue growth at the site of an incision or wound.
