Abstract:
Color developing agents which are derivatives of p-phenylenediamine, e.g. KODAK CD-2(2- amino-5 diethylaminotoluene) and CD-3(4-amino-N-ethylN beta m-toluidine sesquisulfate monohydrate), are known to cause contact allergy. There are two types of reactions to these chemicals. The first one is an acute eczematous lesion, and the other is a lichenoid lesion. A 33-year-old man developed a lichenoid contact dermatitis on both forearms and posterior neck after exposure to a color developing agent. Patch test revealed positive reaction to CD-2. Histopathologic finding from the skin lesion showed a lichen planus-like appearance.
