[Experiences with Langerhans' cell histiocytosis in children in Hungary].

Background: Langerhans cell histiocytosis (LCH) in children is relatively rare, and the long-term analysis of therapy results has not been done yet in Hungary.

Purpose: In this review we summarise the incidence, clinical features, prognostic risk factors and treatment results of children's LCH in Hungary, using data from the National Childhood Cancer Registry in Hungary in a 20-year period between 1981 and 2000.

Results: From January 1981 to December 2000, 111 children under 18 years of age were newly diagnosed with LCH in Hungary.
