Bullous pemphigoid of childhood in Infant/Neonate
Bullous pemphigoid is a chronic autoimmune subepidermal vesiculobullous disease that is most common in older adults. It is rarely seen in infants and children, in whom the precise incidence is unknown.
In the pediatric population, clinical presentation of bullous pemphigoid is variable, with ill-appearing patients who have severe, generalized blisters on one end of the spectrum and patients with localized, asymptomatic lesions on the other. As in adults, pruritic urticarial papules and plaques may precede the formation of bullae. Bullae can be widespread or localized on any body surface. In infants, palms and soles may predominate. Mucosal involvement in children is common.
Genital involvement is reported to occur in just under half of cases. Localized bullous pemphigoid of the genital skin is reported in children aged 7-12. Girls are affected more frequently than boys. When present, this condition can be misdiagnosed as child sexual abuse, and careful consideration must be taken in these cases.
