nabam and Dermatitis--Occupational

We report a patient with occupational contact dermatitis due to sensitization to mancozeb and perhaps metiram used in a vineyard. Patch testing showed strong allergic patch test reactions to 2 of the commercially available preparations used (Dithane Ultra and Polyram WG). Further patch tests showed allergic patch test reactions to mancozeb (0.5 and 1% pet.), a weak reaction to metiram (1% pet.) as well as to 4 other fungicides of the dithiocarbamate group (maneb, nabam, propineb and zineb), which had never been used in the vineyard.
