Langerhans cell histiocytosis

Langerhans cell histiocytosis (LCH) is a rare condition where the body's immune system produces too many Langerhans cells, a type of white blood cell that helps fight infection. This overproduction can form tumors or lesions in various organs, most commonly the bones, skin, and lymph nodes. Symptoms vary widely and may include bone pain, skin rashes, or organ dysfunction. LCH can affect both children and adults, and while some cases resolve on their own, others may require treatment like chemotherapy or radiation. Understanding LCH is important for effective diagnosis and management.
