learn about histiocytosis
Histiocytosis is a group of 'rare' diseases that affect the immune system. If untreated, they are fatal. LCH, HLH, JXG, ECD, DI and RD are the acronyms used for these diseases that were once too 'rare' for a name, so they were coined by the process by which they affected the body. They occur when a white cell known as a histiocyte over produces too many of these. This can cause organ disfunction/failure and tumor growths.
For a list of organizations with additional information and resources for HLH check out the HLH Resources tab above.
