  • In  the follicular type, the cells are arranged in oval or round  nests set up among fibrous connective tissue.
  • At the periphery, the cylindrical cells are arranged in a pallisading pattern reminding of  epithelial basal layer cells. At the centre, cells are located more chaotically and acquire  ‘starry’-like appearance.
  • Between tumor nests are formed either small cavities with clear liquid or larger cystic spaces .
  • They ‘crack’, if the tumor intumescences are compressed.
