Abstract
Seventy (32%) of 222 patients patch tested in our contact dermatitis clinic from 1993 to 1995 had irritant reactions to cobalt. These reactions were " poral" and seemed to reflect a unique and probably toxic effect of cobalt o n the acrosyringium. The reactions are neither follicular nor petechial and we believe they are not allergic. The histopathology of the reactions is d escribed in detail.
