title: Sensitization to triglycidylisocyanurate (TGIC) with cutaneous and respiratory manifestations.
abstract: The case is presented of a man with allergic contact dermatitis and occupational asthma due to triglycidylisocyanurate (TGIC), which is used as a hardener in thermosetting powder paint. The contact dermatitis was confirmed by patch testing (TGIC 0.5% and 5% in petrolatum), and the occupational asthma was confirmed by bronchial provocation testing: two challenges to an aerosol of lactose containing TGIC (0.05% and 0.1%, w/w, each for 0.5+1+2+4 min) led to a maximal decrease in FEV1 of 22% and 31% after 6 and 4 h, respectively. Skin prick tests with unconjugated TGIC were possibly positive. This case confirms that exposure to TGIC in powder paints may cause not only contact dermatitis, but also occupational asthma.
