Juvenile xanthogranuloma with hematological dysfunction treated with 2CDA-AraC.

Juvenile xanthogranuloma was diagnosed in two infants aged 8 and 2 months with skin lesions, hepatosplenomegaly, and pancytopenia. Disease control was not achieved with first-line vinblastine-steroid-VP16 combination therapy. Two courses of 2-chlorodeoxyadenosine (2CDA) (0.3 mg/kg) and cytosine arabinoside (AraC) (1 g/m(2)) were then administered for 5 days and were followed, after hematological recovery, by maintenance therapy. Both patients had normal complete blood cell counts and no signs of JXG, respectively, 31 and 24 months after diagnosis.
