Histiocytosis is a rare blood disease that is caused by an excess of white blood cells called histiocytes. The histiocytes cluster together and can attack the skin, bones, and organs. The disease can range from limited involvement that spontaneously regresses to progressive multi-organ involvement that can be chronic, debilitating and life threatening.
The majority of histiocytosis disorders occur in children under age ten. The disease affects roughly 1 in 200,000 children born each year in the United States. It can also occur in adolescents and adults of all ages. Histiocytosis is so rare that there is little research into its cause and treatment and is often referred to as an "orphan disease", meaning it strikes too few people to guarantee significant government funding.
