Epoxy resins are epoxy polymers that polymerize and crosslink when mixed with a catalyzing agent or "hardener". Most commonly they derive from policondensation of epichlorohydrin and bisphenol-A, forming a mixture of monomers of diglycidyl ether of bisphenol A. Epoxies have excellent adhesion, mechanical and electrical insulating properties and heat resistance. Their applications are therefore extensive and include all sorts of coatings and adhesive materials. In the form of monomers or low molecular weight polymers they are strong irritants and sensitizers. They are an important cause of occupational allergic contact dermatitis (ACD), usually presenting with an airborne pattern, and are by far the first cause of dermatitis among workers of plastics and coatings. 80% of patients react the to epoxy resin present in the standard series. In 20% of cases less common allergens, both epoxy monomers and curing agents, are involved and their identification can be difficult. We report two cases of occupational ACD from epoxy uncommon allergens and review the main characteristics of this entity.
