definition
Localized malformation of dermal collagen, elastic fibres, or glycosaminoglycans. Connective tissue nevi are usually seen in young children as firm, clustered, slightly raised, pea-sized, skin-coloured oval lesions, distributed over the abdomen, back, buttocks, arms, or thighs. They form a characteristic component of a number of inherited disorders such as tuberous sclerosis, but may also occur as isolated lesions without any identifiable genetic basis.
