Dyshidrosis also known as acute vesiculobullous hand eczema, cheiropompholyx, dyshidrotic eczema, pompholyx and podopompholyx) is a skin condition that is characterized by small blisters on the hands or feet. It is an acute, chronic, or recurrent dermatosis of the fingers, palms, and soles, characterized by a sudden onset of many deep-seated pruritic, clear vesicles, later, scaling, fissures and lichenification occur. Many eczema cases which are diagnosed are garden-variety atopic eczema.
This condition do not spread to others, but the compromised integument can increase susceptibility to infection, and the accompanying itching can be a source of psychological distress. The blisters associated with dyshidrosis occur most commonly on the sides of the fingers and the palms, although the soles of the feet also can be affected. The blisters are usually small like the width of a standard pencil lead and found in cluster appearance which is similar to tapioca. The small blisters may merge together to form larger blisters in fatal cases. Skin affected by dyshidrosis is very itchy and more painful when scratched.
The underlying skin may be red and tender once the blisters dry and flake off in about three weeks. Dyshidrosis tends to reoccur regularly for months or years. There are many treatments available for dyshidrosis. However, few of them have been developed or tested specifically on the condition. Topical steroids - while useful, can be dangerous long-term due to the skin-thinning side-effects, which are particularly troublesome in the context of hand dyshidrosis, due to the amount of toxins and bacteria the hands typically come in contact with. Potassium permanganate dilute solution soaks and used to 'dry out' the vesicles and kill off superficial Staphylococcus aureus, but it can also be very painful. Undiluted may cause significant burning.
