Extragenital bullous lichen sclerosus in a pediatric patient: a case report and literature review.

A 14-year-old girl presented with a 1-year history of a pruritic, bullous lesion on her posterior neck. A biopsy revealed bullous lichen sclerosus. Although unusual, this bullous variant of lichen sclerosus is well recognized in the adult literature, but extragenital bullous and hemorrhagic lesions are rare in children. A review of this case and the literature describes the clinical features, pathophysiology, and treatment options for this extragenital bullous variant in an effort to raise awareness of this rare clinical presentation.
