Hematologic involvement portends a poorer prognosis and is the main cause of disease-related death.

Arguments supporting the reactive process are the occurrence of spontaneous remissions, the extensive elaboration of multiple cytokines by the LCH cells and by the T cells in the LCH lesions, and the good survival rate in the patients without organ dysfunction.
