Living with Langerhans cell histiocytosis
A condition in which extra immune cells called Langerhans cells build up in the body, often forming growths in bones and skin.
Understanding Langerhans cell histiocytosis
The extra cells usually form tumors called granulomas. About 80 percent of people have granulomas in the bones, which cause pain and swelling and sometimes fractures. Granulomas also form in the skin as blisters, bumps, or rashes. The pituitary gland may be involved, which can affect puberty and cause diabetes insipidus. In 15 to 20 percent, the lungs, liver, or blood-forming system are involved. Some researchers consider it a form of cancer, though this is debated. It can occur at any time in life.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Bone pain and swelling
- Skin rash or bumps
- Swollen lymph nodes
- Fever
- Cough
- Enlarged liver or spleen
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
