About Histiocytosis Association of Canada
The Histiocytosis Association of Canada provides information to patients and families affected by Langerhans cell histiocytosis, a rare disorder that primarily affects children but may also be found among adults. Although the disease was first described more than 100 years ago, little has been known about it until recent years. In patients with this disease, too many histiocytes (a type of white blood cell) accumulate in certain areas within the body and cause a significantly long list of health problems. The Histiocytosis Association of Canada works to educate affected families and the public and encourages research and relays information to medical professionals.
