"Histiocytosis" is a generic name for syndromes characterized by an abnormal increase in the number of histiocyte cells (also called monocytes, macrophages, or dendritic cells) in the body. It is separated broadly into 3 classes of histiocytoses: (1) Langerhans cell histiocytosis (histiocytosis X); (2) Non-Langerhans cell histiocytosis (hemophagocytic syndromes); (3) malignant histiocytosis syndrome (not discussed here).
