RESUMO
In this retrospective study, 81 patients with photosensitivity were referred to the Contact and Occupational Dermatitis Clinic at The Skin and Cancer Foundation Australia, in Sydney, between 1991 and 1999. Photoallergic contact dermatitis (PACD) was diagnosed in 39.5% of patients, with 87.5% of these reactions being to sunscreen chemicals. Polymorphic light eruption (PMLE) accounted for 19.7% of cases, drug photosensitivity 14.8%, and photoaggravated atopic dermatitis and chronic actinic dermatitis (CAD) each constituted 7.4%. Compared with overseas studies, there was a high incidence of PACD, possibly reflecting the referral bias and widespread use of sunscreens. The incidence of PMLE and CAD was less than studies from cooler climates overseas. No cause could be determined for three photosensitive patients.
