Noneczematous contact dermatitis

摘要

The classic presentation of contact dermatitis is an eczematous reaction but there are less common non-eczematous patterns such as erythema multiforme-like (urticarial) eruption, lichenoid, papular / follicular, bullous, dyshidrosiform, pustular, pigmented, purpuric, lymphomatoid, and granulomatous reactions. They are frequently associated with allergic / irritant contact dermatitis or photocontact dermatitis.
