Localized epidermolysis bullosa, or Weber-Cockayne, is a kind of epidermolysis bullosa simplex. A mutation in a gene in the intermediate keratin filaments 5 and 14 in the lowermost layer of the epidermis causes Weber-Cockayne EBS. Higher mechanical strain, which is common in hyperhidrosis, subsequently results in blister development. EBS has always been tricky to cure.
The condition is distinguished by blisters that appear mainly on the soles and palms and are worsened by physical exertion, prolonged walking, or hot temperature. Hyperhidrosis is a frezuent complication. The rise in blister formation throughout the hot warmer months is assumed to be due to increased skin coefficients of friction produced by sweat and elevated skin temperature.
In addition, localized epidermolysis bullosa is likely not as uncommon as previously thought since individuals frequently don’t perceive themselves to have an issue and hence don’t seek medical assistance.
