Birebeck granules: Electron microscopy ( source)

  • Birebeck granules: these are cytoplasmaic organneles which are tennis raquet shaped and are exclusively seen in Langerhans cells. This is an electron microscopic finding.
  • in case of langerhan cell histiocytosis, a rare type of histiocytosis, the presence of birebeck granules helps in differentiating from other proliferative disorders.
