Allergic contact dermatitis

Abstract

The pathophysiology of ACD follows an intricate design and results in the characteristic, delayed inflammatory response. Although the astute physician may correctly diagnose ACD from its initial, classic history and presentation, alternative diagnoses should be considered and excluded. Patch testing performed with a relevant panel of contact allergens is the ultimate confirmatory test of ACD. Correctly identifying the inciting allergen permits appropriate personal avoidance. Corticosteroids remain the principal treatment options.
