Histiocytic disorders represent clonal disorders of cells believed to be derived from the monocyte, macrophage, and/or dendritic cell lineage presenting with a range of manifestations. Although their nature as clonal versus inflammatory nonclonal conditions have long been debated, recent studies identified numerous somatic mutations that activate mitogen-activated protein kinase signaling in clinically and histologically diverse forms of histiocytosis. Clinical trials and case series have revealed that targeting aberrant kinase signaling using BRAF and/or MEK inhibitors may be effective. These findings suggest that a personalized approach in which patient-specific alterations are identified and targeted may be a critically important therapeutic approach.
