Pulmonary Langerhans Cell Histiocytosis

Pulmonary Langerhans Cell Histiocytosis (LCH) is a rare lung disease where a type of immune cell called Langerhans cells accumulate in the lungs. This buildup can damage lung tissue and disrupt normal breathing. Often linked to smoking, it can cause symptoms like coughing, shortness of breath, and chest pain. In the context of interstitial lung disease, which affects the lung’s supportive tissue, LCH can cause scarring and inflammation, making it harder for the lungs to function properly. Treatment may involve stopping smoking, medications, or other therapies to manage symptoms and improve lung health.
