Dyshidrosis is a type of dermatitis that is characterized by itchy blisters on the palms of the hands and bottoms of the feet.[5] Blisters are generally one to two millimeters in size and heal over three weeks.[6][7] However, they often recur.[7] Redness is not usually present.[6] Repeated attacks may result in fissures and skin thickening.[6]
The cause is unknown.[7] Triggers may include allergens, physical or mental stress, frequent hand washing, or metals.[7] Diagnosis is typically based on what it looks like and the symptoms.[7] Allergy testing and culture may be done to rule out other problems.[7] Other conditions that produce similar symptoms include pustular psoriasis and scabies.[6]
Avoiding triggers may be useful, as may a barrier cream.[6] Treatment is generally with steroid cream.[7] High strength steroid creams may be required for the first week or two.[6] Antihistamines may be used to help with the itch.[7] If this is not effective steroid pills, tacrolimus, or psoralen plus ultraviolet A (PUVA) may be tried.[6][7]
About 1 in 2,000 people are affected in Sweden.[6] Males and females appear to be affected equally.[6] It explains about one in five cases of hand dermatitis.[8] The first description was in 1873.[6] The name comes from the word "dyshidrotic", meaning "difficult sweating", as problems with sweating was once believed to be the cause.[6]
