title: Contact dermatitis to multiple exotic woods.
abstract: Occupational contact dermatitis to individual wood species from foreign countries, such as Asia, Africa, Central America, and South America, has been described. This report concerns the case of a domestic woodworker who developed allergic contact dermatitis shortly after beginning to work with multiple exotic woods. Patch testing with domestic and exotic wood fresh sawdust samples, 1% and 10% in petrolatum, yielded strong positive reactions to six exotic woods: zericote, pao ferro, cocobolo, becote, macassar ebony, and padauk. Later testing confirmed sensitivity to the allergenic quinonoid constituents in pao ferro (R-3,4-dimethoxydalbergione), cocobolo (obtusaquinone), and macassar ebony (macassar quinone).
