[Allergic contact dermatitis from colophony and turpentine in resins of untreated pine wood].

Pine wood is one of the most used raw products in furniture manufacturing in Europe. High concentrations of colophony and turpentine can be extracted from pine resins. A 45-year-old woman developed a contact dermatitis of the face and hands due to a sensitization to colophony and turpentine after she had bought untreated pine chairs. The increased use of untreated pine in the furniture industry might result in an increase of colophony and turpentine-induced contact allergies. Therefore, the slogan "untreated=harmless" should be considered critically in such cases.
