Langerhans cell histiocytosis (LCH): Working to change pediatric cancer outcomes, one patient at a time

Langerhans cell histiocytosis (LCH) is a rare disorder where the body makes too many dendritic cells. Dendritic cells are a form of white blood cells. These cells play a role in the body’s immune system. LCH most commonly affects the skin and bones, but can involve any organ in the body, including lymph nodes, lungs, liver, spleen, bone marrow or brain.

Symptoms of LCH can vary depending on the part of the body that is affected. Some common symptoms include:

• Pain in the stomach or pelvis

• Lumps or lesions on the skull, upper or lower limbs, hands or feet, ribs, pelvis and spine 

• Skin issues, including a skin rash or cradle cap (a scalp rash often in infants)

• Ear pain or recurring ear infections

• Tiredness

• Fever or sweats

• Hair loss

• Yellow skin

• Vomiting and diarrhea

• Blood in the stool

• Enlarged liver or spleen

• Increased thirst

• Rapid weight change

• Problems breathing or shortness of breath

• Loss of hearing

• Blurred or loss of vision

• Swollen or bleeding gums

• Swollen lymph nodes

• Low-risk LCH involves the skin, bones, lymph nodes and brain. It can also involve multiple organs, but will generally not affect liver, bone marrow or spleen. Some children with low-risk LCH may improve without therapy. If just a single bone is affected, surgery is usually the first step. The surgery is used to confirm the diagnosis and could remove the dendritic cell growth. Doctors watch your child carefully afterward to check for a possible return of LCH.

• High-risk LCH involves multiple organs, including the liver, bone marrow or spleen. For children with high-risk LCH, the best treatment is chemotherapy that lasts for about a year. Chemotherapy are drugs that kill cancer.
