title: [Uncommon manifestations of atopic dermatitis].
abstract: Atopic dermatitis is an inflammatory process characterized by a series of cutaneous alterations of typical morphology and distribution, with intense pruritus of nocturnal predominance, of chronic evolution, stational appearance, and with personal and family history of atopy. On genetically predisposed skin, dry and hypersensitive, the immune factors and other types are implicated in determining the abnormal reactions to multiple endogenous and environmental factors. The diagnosis is clinical, generally obtained by a group of signs and symptoms known as the Hanifin and Rajka criteria. The patients with atopic dermatitis can present with clinical typical manifestations, or minimized and localized variations as well, considered a stigma of atopic constituent. In some patients there can be observed clinical and morphological variations with special localizations denominated atypical variations of atopic dermatitis. The identification of these atypical presentations of atopic dermatitis leads to the differential diagnosis, with an early establishment of the disease's diagnosis and the appropriate and early treatment.
