Atopic dermatitis with typical and atypical manifestations / 中华皮肤科杂志

ABSTRACT

Atopic dermatitis (AD) is a highly heterogeneous skin disease with various clinical manifestations. Early studies mainly focused on infant-onset AD, which is characterized by typical skin lesions such as eczematous dermatitis on the flexor sites accompanied by genetic predisposition to other allergic diseases; however, atypical manifestations and distributions of skin lesions are common among adult AD and elderly AD, e.g., distribution mainly on the extensor sites and polymorphic rashes such as prurigo nodularis. Many dermatologists are not familiar with atypical manifestations of AD, including atypical manifestations and distributions of skin lesions as well as atypical age at onset, which decreases the diagnostic rate of AD to a certain extent. This article delineates clinical features of AD with typical and atypical manifestations, in order to promote the understanding of AD among Chinese dermatologists.
