Abstract

Cyanamide is a chemical substance used in the treatment of chronic alcoholism as well in agriculture as a fertilizer. We report the case of a 28-year-old healthy non-atopic man that developed a severe skin eruption after the accidental penetration of a small amount of Dormex® (a plant growth regulator containing cyanamide) through the patient's gloves. Patch tests revealed positive reactions to Dormex® 1% pet. and cyanamide at a dilution of 0.1% pet. and 1% pet. We discuss the causes of sensitization in a patients that regularly used protective measures during anti-parasites treatments.
