Childhood anogenital lichen sclerosus. A case report.

Childhood lichen sclerosus is a rare disorder. A 4-year-old girl with chronic vulvar pruritus who was initially suspected to be the victim of child abuse was treated. Vulvar biopsy was performed, confirming the diagnosis of lichen sclerosus. The child was treated with 2% progesterone cream, with complete resolution of her pruritic symptoms and signs of traumatic injury to the vulvar skin. The basic condition, lichen sclerosus, has persisted.
