title: Congenital self-healing Langerhans cell histiocytosis with persistent cellular immunological abnormalities.
abstract: We describe an infant who presented at birth with numerous haemorrhagic and encrusted skin lesions, hepatomegaly, lymphadenopathy, raised hepatic transaminases, leucopenia and thrombocytopenia. The diagnosis of Langerhans cell histiocytosis was confirmed by immunohistochemistry, which demonstrated the presence of CD1, S-100 and DR positive cells in the skin infiltrate. The skin lesions resolved spontaneously after 6 weeks but recurred at 3 months and again were self involuting with resolution by 9 months. Persistent circulating T-cell abnormalities, including T-cell lymphopenia and the presence and persistence of peripheral blood CD1 + cells were noted throughout the first year of life.
