Hemophagocytic Lymphohistiocytosis

Hemophagocytic lymphohistiocytosis (also called hemophagocytic syndrome or “HLH disease”) is a blood and immune system disorder that mainly affects infants and young children who are born with it. However, it can happen to children at any age due to illnesses like cancer or viral infections. Because it is rare and possibly life-threatening, early diagnosis and care is critical. 

Our hematologists (blood disorder specialists) in the Nemours Children's Center for Cancer and Blood Disorders work together to identify HLH disease as quickly as possible. We also include specialists in immune disorders to help us plan the most effective treatment for your child.  

Since autoimmune care in children is much different than in adults, you can rely on our pediatric experience to help us identify the cause of your child’s symptoms, and to help you through every step of your child’s medical journey.
