Occupational contact dermatitis: etiology, prevalence, and resultant impairment/disability.

Abstract

Cutaneous irritant and allergic responses account for the vast majority of cases of occupational contact dermatitis (OCD). Although the pathophysiologic responses to these two different exposures are distinct, the clinical differentiation between chronic cumulative irritant contact dermatitis and allergic contact dermatitis can be difficult and frequently requires patch testing. This article reviews the recommended algorithms that clinicians should utilize to assess whether a worker suffers from OCD. The prevalence of OCD, its predisposing factors (both endogenous and exogenous), and prognosis are discussed in depth. Finally, issues surrounding the assessment of impairment and disability resulting from OCD are summarized.
