Summary

Description
English: Very high magnification micrograph of an ameloblastoma. H&E stain.

The images show the characteristic features:

  • Islands of cells with palisaded nuclei that have reverse polarization.
    • Reverse polarization of nuclei = nuclei distant from the basement membrane/nuclei at pole opposite of basement membrane.
    • Palisaded nuclei = picket fence appearance; columnar-shaped nuclei with long axis perpendicular to the basement membrane.
  • Subnuclear vacuolization in palisading cell - vacuoles at the basement membrane aspect.
  • Loose stroma around the islands of cells.
  • Star-like cells at the centre of the islands of cells (stellate reticulum).
  • Low mag.
