[Occupational dermatitis: irritation or allergy?].

Abstract

Occupational dermatitis is a very frequent subject of consultation, as much in general practice as in dermatology. The most frequently found pathologies are linked to environmental factors. In these cases, irritant dermatitis and allergic contact dermatitis represent the majority of the cutaneous problems. Rigorous history taking associated with an attentive examination and a few investigations, essentially consisting of skin testing, form an incontestable tripod. The therapeutic approach, as much preventative as curative, can only be envisaged after having made a precise diagnosis, of which the conclusions should be pertinent and adapted to each patient presenting in consultation. In occupational disease, the distinction between irritant dermatitis and allergic contact dermatitis is primordial.
