GHOST CELLS (SHADOW CELLS)

🔷 Introduction:

Ghost cells are altered epithelial cells characterized by the loss of Nuclei with presence of basic cell outline.

➡️ Lesions showing Ghost cells:-
  1. COC & dentinogenic ghost cell tumour
  2. Odontomas
  3. Ameloblastomas (Pituitary)
  4. Ameloblastic fibro-odontoma
  5. Ameloblastic Odontoma
▪️Characteristic Features:
  • Ghost cell change occurs due to coagulative Necrosis or a form of Normal/aberrant keratinization of odontogenic epithelium.
  • Masses of ghost cells may fuse to form large sheets of amorphous, acellular material.
  • Calcifications with them is common.
  • Appear as basophilic granules- ⬆️ in size & no. – form extensive masses of calcified material.
  • Areas of eosinophilic matrix material represent dysplastic dentin(dentinoid) present adjacent to epithelial component.
  • Ghost cell contain –
  1. Nuclear Remnants
  2. Remnants of cytoplasmic organelles
  3. Numerous tonofilaments
  • Ghost cell differ from normal keratotic squames – they are larger, vacuolated & remnants of nuclear membrane are more prominent.
  • This may be due to intracellular edema & presence of dilated degenerated membranous organelles.
  • Ghost cells are immuno-reactive for Amelogenin (enamel protein).
