Abstract
Skin responses to ultraviolet irradiation in patients with atopic dermatitis were
studied to evaluate the role of sunlight in the exacerbation of atopic dermatitis.
A total of 15 patients, seven males and eight females, with atopic dermatitis who
complained of exacerbation of their dermatitis after sun exposure were examined by
photo testing with UVB and UVA irradiation and photopatch tests. Nine out of 15 patients
showed abnormal skin reactions. Lowered minimal erythema doses (MEDs) to a single
exposure of UVB, papular or erythematous responses after single or repeated exposures
to UVB or UVA and positive photopatch test reactions to sunscreen ingredients and
fragrances were found. There are apparently multiple mechanisms of photoexacerbation
in patients with atopic dermatitis.
