||Airborne allergic contact urticaria from methylhexahydrophthalic anhydride and hexahydrophthalic anhydride
||Dec. 1999, Vol.41, No.6, p.339-341. Illus. 15 ref.
||A 32-year-old atopic man began to work as a winder in an electrical machine manufacturing plant. Within a few months he developed rhinitis and conjunctivitis, but he waited 7 years before seeing a doctor about it. He also developed work-related pruritus and redness on his arms and face. He worked in an area where methylhexahydrophthalic anhydride (MHHPA) and hexahydrophthalic anhydride (HHPA) were used to harden epoxy resins. Patch testing was negative. An open application test showed a strong urticarial follicular reaction with MHHPA and a provocation test with this substance was positive. Provocation testing with HHPA was negative when diluted. Applied undiluted, HHPA provoked whealing. It was concluded that the patient had occupational allergic contact urticaria from MHHPA and HHPA. Occupational rhinitis from HHPA was also diagnosed from prick tests and RASTs. A change of job was recommended.
