Overview

Langerhans cell histiocytosis (LCH) is a disorder that primarily affects children, but is also found in adults of all ages. People with LCH produce too many Langerhans cells or histiocytes, a form of white blood cell found in healthy people that is supposed to protect the body from infection. In people with LCH, these cells multiply excessively and build up in certain areas of the body, causing tumors called granulomas to form. The symptoms vary among affected individuals, and the cause of LCH is unknown. In most cases, this condition is not life-threatening. Some people do experience life-long problems associated with LCH.[1]
