AbstractPatch testing, using European standard allergens and suspected causative substances brought in by patients, was carried out in 490 patients with eczema in Hong Kong and 437 completed the test. Before patch testing, 244, 141 and 105 patients were diagnosed as having contact dermatitis, endogenous eczema and unclassified eczema, respectively. After patch testing, the diagnosis of the causal agent was changed in 54 contact dermatitis patients, and 18% of endogenous eczema patients and 34% of unclassified eczema patients were re-diagnosed as contact dermatitis. In the patients with a final diagnosis of contact dermatitis, 19.5% were positive to fragrance mix, followed by nickel sulfate (16.4%) and cobalt chloride (11.3%). The commonest causative agents for contact dermatitis were soap or detergent (22.0%) and traditional Chinese medicine (17.3%); the latter was a more common cause of contact dermatitis than Western medicine (9.0%) or metals (13.4%). The prevalence of allergic reaction to fragrance in Hong Kong was higher than among Chinese in Beijing, Shanghai, Taipei or Singapore (78% ethnic Chinese). Dermatologists should have a high index of suspicion about traditional medications and should patch test with the suspected substance when patients give a history of use.
