WebbLangerhans cells constitute a morphologically well characterised subpopulation (3–8%) of mammalian epidermal cells which, in contrast to the bulk of epidermal cells, bear Fc-IgG and C3 receptors ... 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.

WebbMultinucleated giant cells found in granulomas of tuberculosis have traditionally been called Langhans GCs. However, similar GCs can be seen in other granulomas as well. Note that these cells are different from epidermal mononuclear macrophages known as Langerhans cells, named after the scientist who discovered the islets of Langerhans. WebbWhile Langerhans cells are found in normal, healthy persons, an over-production and build-up of these cells can lead to organ damage. As we have learned much more about the biology of LCH, we now know that the disease does not actually originate from Langerhans cell, but from a more immature cell called a myeloid dendritic cell.

WebbLanghans giant cells are named after Theodor Langhans (1839–1915), a German pathologist. They should not be confused with Langerhans cells, which are mononuclear epidermal dendritic cells derived (like Langhans cells) from monocytes and named after Paul Langerhans.
