Occupational dermatoses contribute to a significant portion of work-related diseases. Irritant contact dermatitis does not involve immunological factors, but results when repair capacity of skin is exhausted or when the penetration of chemicals excites an inflammatory response. Irritants affect everyone, though individual susceptibility varies greatly with regard to development. Plants in the Anacardiaceae family, which includes cashewnut tree, is a frequent cause of contact dermatitis worldwide. Recognition of clinical patterns and geographic variations in occupational skin diseases helps to further strengthen future research in these areas, as well as improving their management. We report a case of acute irritant contact dermatitis following contact with cashewnut shell.
