Dyshidrotic eczema (pompholyx) is an itchy, chronic, recurrent, often symmetric eruption on the palms of hands, fingers, and soles of the feet. It is characterised by small, deep-seated, 1–2 mm fluid-filled vesicles on these sites, which resolve after several weeks with scaling.

Dyshidrotic eczema is a sudden rash of small, itchy blisters on your palms and along the sides of your fingers. This skin condition can also make blisters pop up on the soles of your feet or on your toes. Your doctor might call it by other names, including dyshidrosis, foot-and-hand eczema, pompholyx, vesicular eczema, or palmoplantar eczema.
