Barata AR, Conde-Salazar L - An Bras Dermatol (2013 Jul-Aug)

Bottom Line: Clinically it presents as a chronic hand and/or forearms eczema of occupational origin, especially in professionals who work as food handlers.The most sensitive and practical is the prick-by-prick test with food that the patient refers to cause intense itching after immediate skin contact.Treatment is symptomatic, and it is mandatory to avoid the responsible allergen, wearing plastic gloves and even sometimes leaving the workplace for symptom resolution.

ABSTRACT
Protein contact dermatitis is a skin condition not well known and underdiagnosed by dermatologists, resulting from an IgE-mediated allergic reaction. Clinically it presents as a chronic hand and/or forearms eczema of occupational origin, especially in professionals who work as food handlers. Epicutaneous tests are negative, and to diagnose this condition it is necessary to perform immediate-type allergy tests. The most sensitive and practical is the prick-by-prick test with food that the patient refers to cause intense itching after immediate skin contact. Treatment is symptomatic, and it is mandatory to avoid the responsible allergen, wearing plastic gloves and even sometimes leaving the workplace for symptom resolution.

Mentions: Given the clinical aspect, location of the lesions and the patient's occupation, wedecided to conduct patch testing with the baseline series of the Spanish Group forResearch of Allergy and Contact Dermatitis and the rubber series (True Test andChemotechnique Diagnostics), in addition to prick-by-prick tests with all the raw foodthat the patient handled daily at her workplace. All patch tests were negative.Regarding the prickby-prick tests, positive results were observed to crab, tuna fish,salmon, scallop, eel, shrimp and butterfish (Figure3). Additionally IgE levels were measured in serum, with high levels of totalIgE (326 IU / ml), shrimp IgE (0.52 KU / L) and crab IgE (0.52 KU / L).
