Typical case of dyshidrosis of the hand.
Dyshidrosis is an acute or subacute eczema of the hands and feet, which was formerly erroneously regarded as a disorder of the sweat glands.
The eczema is caused by toxic, subtoxic, allergic or atopic causes. The hyperhidrosis is a common underlying condition and can also cause blisters.
Characteristic of the dyshidrotic eczema are many tense tense blisters on the hands and soles of the feet that itch severely. The fluid in the blisters is clear or slightly yellow. The coalescence of these blisters is called "pompholyx". The bacterial or fungal superinfection is a complication of the disease.
