Overview

The authors describe a case of allergic contact eczema of the hands, forearms, face and thighs in a 28-year-old woman engagedin the production of insulin and heparin in a large pharmaceutical firm. The afflicted female was systematically in contact for 18months with surface disinfectant based on aldehydes and quaternary ammonium compounds .Allergological examination revealed atopy restricted to a narrow spectrum of inhaled allergens, epicutaneous tests with glu-tar(di)aldehyde (0.25% aq.), benzalkonium chloride (0.1% vas.).were positive (2+), latex gloves negative, in standard and drugtests only an irrelevant reaction to merthiolate was found (1+).The prerequisite of proper examination and subsequent prevention is detailed knowledge of the composition and availability ofdifferent constituents of the composite disinfectant for the implementation of special epicutaneous tests. The authors discuss theoccurrence and use of benzalkonium chloride incl. its presence in some drugs for external use.
