Erdheim-Chester disease (ECD) is a rare multisystem disorder of adulthood. It is characterized by excessive production and accumulation of histiocytes within multiple tissues and organs. Histiocytes are large phagocytic cells (macrophages) that normally play a role in responding to infection and injury. (A phagocytic cell is any "scavenger cell" that engulfs and destroys invading microorganisms or cellular debris.) In those with ECD, sites of involvement may include the long bones, skin, tissues behind the eyeballs, lungs, brain, pituitary gland, and/or additional tissues and organs. Associated symptoms and findings and disease course depend on the specific location and extent of such involvement. The specific underlying cause of ECD is unknown.
