ABSTRACT

Background: Phytodermatitis are frequently seen in dermatological practice. In the Yucatan Peninsula we have observed an skin reaction caused by urushiol. We did not find any previous reports in the dermatological literature.
Objetive: To identify clinical features of dermatitis caused by Metopium Brownei.
Methods: We report a retrospective study of 20 cases. We registered: age, sex, occupation, geographic location of the tree, time of onset of the first manifestations, topography, morphology, and clinical diagnosis. Epicutaneous test were not performed. Eczema was the usual reaction. Diagnosis of probably allergic contact dermatitis was made in 9 patients (45%). 30% of the patients offered data of either irritant and/or allergic contact dermatitis, 1% presented probably photosensitivity and 1% airborne contact dermatitis.
Conclusions: Reactions to Metopium Brownei correspond probably to a local or systemic allergic process, but clinical manifestations of airborne or photosensitivity could also occur. Clinical features are very similar to those observed with poison ivy and the other phytodermatitis caused by urushiol. The great affluence of tourist to the Yucatan Peninsula allows to suppose that this dermatitis can be observed anywhere in the world and its recognition can be useful for the dermatological community that is not a resident in the endemic zones.
