Blistering diseases in children. How to recognize and treat the most common.

The most common blistering diseases encountered in children are impetigo, burns, acute dermatitis, friction blisters, viral blisters, insect bite reactions, and linear IgA dermatosis. Diagnosis should be based on specific clinical manifestations and, when necessary, results of a Tzanck test or skin biopsy. A search for an intact blister is always warranted when erosions, oozing, or crusts are noted.
