Childhood bullous pemphigoid in association with hyperimmunoglobulin E syndrome.

Bullous pemphigoid is an acquired immunobullous disorder affecting predominantly the elderly. It is very rare in children and exceptional in infants. Hyperimmunoglobulin E syndrome is a rare primary immunodeficiency characterized by a triad of high serum levels of polyclonal immunoglobulin E with peripheral eosinophilia, recurrent staphylococcal infections of the skin and lungs, and pruritic dermatitis. Variable associated features include coarse facies, cold cutaneous abscesses, and osteopenia. This report describes, to the best of my knowledge, the first instance of childhood bullous pemphigoid associated with hyperimmunoglobulin E syndrome in a 6-month-old boy.
