Dyshidrosis, a form of dermatitis, is a skin condition characterized by small blisters on the hands and feet, particularly on the palms and soles. Dyshidrosis blisters may be present for a maximum of three to four weeks, although the condition itself may be either acute, chronic, or recurrent. The condition is also known as dyshidrotic eczema, dyshidrotic dermatitis, or pompholyx.


Causes and risk factors:

The cause behind dyshidrosis is not known, however, it has been associated with atopic dermatitis, as well as asthma, hay fever, and other allergies and allergic conditions. Dyshidrosis is not contagious, and may not be spread from person-to-person, despite the fact that its appearance may be frightening.


Symptoms:

Dyshidrosis symptoms may vary in any particular case, and some possible symptoms may include:

Cracked skin
Itching
Blisters
Fissures
Pain (from blisters)
Pitted nails (fingernails and toenails)
Swollen lymph nodes
Vesicles (blisters with fluid)


Diagnosis

Dyshidrosis is diagnosed by a doctor or medical professional. A physical examination is the typical method, although other procedures such as a skin biopsy, KOH test, or patch test may also be used in certain circumstances.

Treatment:

Dyshidrosis is frequently treated with topical creams and ointments. Other common methods include antihistamines, and wet or cold compresses. In cases where none of the aforementioned treatments are helping the patient, ultraviolet light therapy known as psoralen plus ultraviolet A (PUVA) may be an option.

Although dyshidrosis treatment is possible with these methods, the incidence of recurrence is high, and in some cases, dyshidrosis is a chronic condition. Avoiding exposure to certain chemicals and substances which are triggers may be beneficial in prevention of outbreaks. Reducing stress is also thought to be of assistance in prevention.
