title: Congenital self-healing reticulohistiocytosis--report of a case of the solitary type and review of the literature.
abstract: A 2-month-old female infant presented with a single hemorrhagic crusted papule on the chin present since birth. No visceral involvement could be demonstrated. The lesion involuted spontaneously with scarring in 3 months. Mononuclear cells in the cutaneous infiltrate were Langerhans cells with typical Birbeck granules which positively stained with S-100 protein. This case is the solitary type of congenital self-healing reticulohistiocytosis.
