What causes eosinophilic granulomas?

Eosinophilic granulomas are a form of Langerhans cell histiocytosis (also called histiocytosis X). Langerhans cell histiocytosis is an autoimmune disease that makes your child’s body produce too many white blood cells that usually fight infections.

Eventually, these extra white blood cells can clump together and form tumors throughout your child’s body.
