To the Editor.—
The high technology electronics industry requires the use of fast-curing resins in the production of the newer electronic hardware. I saw a patient who had allergic contact dermatitis to an aliphatic diisocyanate monomer that was recently introduced into the manufacture of a new electronic part.
Report of a Case.—
A 48-year-old woman (an engineering aid) began working with the monomer, methylene bis (4-cyclohexylisocyanate) (Flurane 88202A), and a polyol-type catalyst (Flurane 88202B). She had been working with these compounds for one week when she suddenly had a pruritic, erythematous dermatitis on her right forearm, face, and neck. She had been instructed to take precautions with the use of these new compounds by working under a hood and wearing gloves, since they were known to have irritating effects on the skin, eyes, and respiratory tract. The eruption cleared following a course of corticosteroids given for systemic effect. Three weeks
