​What is Pathology –What are Langhans Gigantic Cells ? 
 Langhans gigantic cells (GCs) are a type of cell found in Langhans. Langhans GCs, or multinucleated giant cells, are multinucleated giant cells observed in tuberculosis granulomas. Similar GCs can, however, be found in other granulomas. These cells are not to be confused with epidermal mononuclear macrophages known as Langerhans cells, which are named after the scientist who discovered the Langerhans islets. They were previously distinguished from other multinucleated GCs including Touton GC (found in xanthogranulomas) and Warthin–Finkeldey GC (found in measles). All of these cells are made up of epithelioid macrophages that have fused together, thus it's pointless to separate
