Inclusion Criteria:
1.DISEASE CHARACTERISTICS:
- Histopathologically confirmed diagnosis of Langerhans cell histiocytosis according to the criteria defined by the Histiocyte Society
- Demonstration of CD1a antigenic determinants on the surface of lesional cells (by immunocytology or immunohistology) or Birbeck granules in lesional cells by electron microscopy
-
Considered at risk or low risk according to the following criteria:
