Dyshidrotic eczema (also called pompholyx or acute vesiculobullous hand eczema) is the abrupt appearance of deep-seated, 1- to 2-mm vesicles on the sides of the fingers, palms, and soles. The vesicles are extremely pruritic, may coalesce into larger bullae, and may rupture to become dry or fissured. The outbreak usually resolves over a few weeks unless secondary infection develops. The differential includes bullous tinea, id reaction, scabies infestation, or allergic contact dermatitis.
Management and Disposition
Treatment includes a high-potency topical steroid and prevention of secondary infection. Refer to a dermatologist for long-term treatment; this is often chronic with the potential for significant disability.
The initial lesions resemble tapioca pudding.
These lesions wax and wane and are often exacerbated by stressful life events.
