Langerhans Cell Histiocytosis
Histiocytosis XLCH
📋Overview
Langerhans Cell Histiocytosis (LCH) is a rare disorder characterized by the abnormal proliferation of Langerhans cells, a type of dendritic cell involved in immune response. It is considered a clonal neoplastic disease with inflammatory features. LCH can affect various organs, including bone, skin, lymph nodes, lungs, and the pituitary gland. The term Langerhans Cell Histiocytosis has replaced older eponyms such as Histiocytosis X, which included subtypes like eosinophilic granuloma, Hand-Schüller-Christian disease, and Letterer-Siwe disease.
