Periorbital contact dermatitis due to yellow mercuric oxide

Abstract

SHORT COMMUNICATIONS quite sporadic, caused respiratory distress right from the beginning, and finally produced active sensitization in a control (6), confirm its strong irritant and allergic potentials.Although sensitized to Dalbergia latifolia Roxb., whose main allergen is (R)-4-methoxy dalbergione, both patients reacted to the other dalbergiones, in particular to (R)-3,4-dimethoxy delbergione. As this specific allergen, the strongest known sensitizing dalbergione (7), occurs only in pao ferro (Machaerium scleroxyum Tul.), this response must be considered a cross-reaction.
