Abstract
Colophony is a resin, obtained from pine trees. It has many applications in industry as well as in products for everyday life and exposure is virtually impossible to avoid. In article, we concentrate on occupational exposure, which is frequent in workers in electronics, furniture and paper industry, production of adhesives, plastics, printing ink and synthetic rubber as well as in everyone, daily in contact with products, which contain colophony, or pine wood, like carpenters and woodworkers. Main allergens are oxidation products of abietic-type acids, but cross-reactivity with fragrances, wood resins, Balsam of Peru, wood tar and oil of turpentine is also possible. Exposure to colophony manifests itself on skin in allergic patients mainly as allergic contact dermatitis. The diagnosis is based on history of exposure, clinical presentation and epicutaneous testing. Although the only effective treatment is complete avoidance of exposure, it is difficult to avoid colophony. Consequently, prophylaxis is essential and concentrates on safe working practices, personal hygiene and protection.
