Dyshidrotic dermatitis in Adult
Alerts and Notices
Synopsis
Dyshidrotic eczema can be associated with atopic dermatitis, contact irritants and allergens, dermatophyte and bacterial infections, hyperhidrosis, hot weather, high dietary intake of nickel or cobalt, and emotional stress. Administration of intravenous immunoglobulin (IVIG) has been associated with severe dyshidrotic dermatitis. There have also been a few reports of dyshidrotic dermatitis in patients treated with secukinumab.
Some cases spontaneously resolve. Treatment is aimed at symptomatic relief and control of vesiculation.

Differential Diagnosis & Pitfalls
- Allergic contact dermatitis – Distinguishing idiopathic dyshidrotic dermatitis from allergic contact dermatitis can be difficult, although contact dermatitis often involves the dorsum of the hand. An extensive history of environmental exposure should be gathered when a vesicular hand rash is present.

- Dermatophyte infection (eg, tinea pedis and/or manuum)
- Herpetic whitlow
