A case of protein contact dermatitis / 천식및알레르기

ABSTRACT

A 24-year-old woman complained of chronic eczematous lichenified skin lesions with itching on both hands. The lesions were distributed mainly on the lateral and dorsal sides of the fingers. She had a history of atopic dermatitis and noticed itching sensation followed by erythema within minutes of contact with salmon at the respective contact sites, and subsequent formation of papules. Additionally, the ingestion of salmon resulted in swelling on her lips and throat. She had been working as a cook for 2 years and her sister had suffered from allergy to metal. Patch test with Korean standards and bakery series yielded positive to nickel and cobalt without clinical relevance. In a standardized skin prick test, strongly positive reactions to raw salmon and red snapper were observed after 20 min, but a patch test with the same substances was negative. We report a case of protein contact dermatitis due to salmon and red snapper.
