Airborne occupational contact dermatitis from epoxy resin in an immersion oil used for microscopy

An 8-year experience in airborne contact dermatitis

OBJECTIVE

A large number of case reports concerning occupational airborne contact dermatitis have been published in the last few years. Our purpose was to establish the prevalence of airborne contact dermatitis in a routinely patch-tested population and to obtain further epidemiologic data.

METHODS

In a single-center study, the data of 5,092 routinely patch-tested patients were collected using a standardized questionnaire and a documentation form. The study period extended from October 1994 to March 2002.

RESULTS

The clinical diagnosis was airborne contact dermatitis in 15 cases (0.29%). Patch testing revealed positive and relevant results in nine patients (0.18%). Plant or wood extracts were the sensitizers in all cases but two, and perfume and epoxy resin were the sensitizers in one case each. The diagnosis of an irritant airborne contact dermatitis was established in six patients. A relationship with occupation was found in seven cases (0.14%) when 'housewife' was included as an occupational category and in five cases (0.1%) when this was excluded.

CONCLUSION

Airborne contact dermatitis is a rare diagnosis in an unselected patch-test population. An occupational relationship was less common than has been implied in case reports in recent years.

An update on airborne contact dermatitis

This review is an update of 2 previously published articles on airborne contact dermatoses. Because reports in the literature often omit the term 'airborne', 18 volumes of Contact Dermatitis (April 1991-June 2000), 8 volumes of the American Journal of Contact Dermatitis (1992 1999) and 4 volumes of La Lettre du Gerda (1996-1999) were screened, and the cases cited were classified as to history, lesion locations, sensitization sources, and other factors. Reports on airborne dermatitis are increasingly being published, sometimes in relation to specific occupational areas.
