Webb1 mars 2024 · Langerhans Cell Histiocytosis (LCH) is a collection of rare disorders of the mononuclear phagocytes and dendritic cells. Other disorders similar to LCH include Histiocytoses Rosai-Dorfman, juvenile xanthogranuloma, and Erdheim-Chester diseasebut they do not share the exact phenotypic signature of LCH. Contents 1Disease Entity … WebbLangerhans cells are seen in all suprabasal layer of stratified squamous epithelium. They play a vital role in local defense mechanisms in the epithelium. They are bone marrow derived dendritic cell and act as antigen presenting cells (APCs) of immune responses. APCs, the lymphocytes respond to specific microbes.
