Robin; Hoang, Mai P. Arguments supporting the reactive nature of LCH include the occurrence of spontaneous remissions, the extensive secretion of multiple cytokines by dendritic cells and bystander-cells a phenomenon known as cytokine storm in the lesional tissue, favorable prognosis and relatively good survival rate in patients without organ dysfunction or risk organ involvement.

The pathogenesis of Langerhans cell histiocytosis LCH is a matter of debate. On the other hand, the infiltration of organs by monoclonal population of pathologic cells, and the successful treatment of subset of disseminated disease using chemotherapeutic regimens are all consistent with a neoplastic process. Guidelines for management of patients up to 18 years with Langerhans cell histiocytosis have been suggested.

Multifocal multisystem LCH, also called Letterer-Siwe diseaseis a rapidly progressing disease in which Langerhans Cell cells proliferate in many tissues.
