Localized vulvar bullous pemphigoid of childhood: A rare cause of persistent vulvar erosions in children.

Localized vulvar bullous pemphigoid of childhood is an excessively rare variant of bullous pemphigoid and affects almost exclusively young girls of 7-12 years of age. In contrast to adult-onset bullous pemphigoid, a prompt response to potent topical corticosteroids is observed in the majority of cases, with a favorable prognosis and rare relapses. We report the case of a 7-year-old girl who presented with this condition. Our case reinforces the recognition of this rare subtype of childhood bullous pemphigoid as a distinct entity and enlightens the importance of performing a cutaneous biopsy when clinically indicated.
