Of 149 workers from the electronics industry with occupational dermatoses seen at the Joint Occupational Dermatoses Clinic at the National Skin Centre, Singapore, 51.0% (76) were diagnosed to have irritant contact dermatitis, 40.9% (61) had allergic contact dermatitis, and 8.1% (12) had noncontact dermatitis. More than half of the patients were younger than 30 years of age. Common irritants were soldering flux, oils and coolants, solvents, and acids/alkalis. The most common allergens were nickel and resins, followed by rubber chemicals and the constituents of flux. Of the noncontact dermatitis, 8 were caused by occupationally relevent exacerbation of endogenous eczema, whereas there was one case each of miliaria, frictional dermatitis, and fatal toxic epidermal necrolysis caused by trichloroethylene allergy.
