  • Figure 1.
    Figure 1.

    Different aspects of maxillary ameloblastomas. (A) Follicular pattern, showing large cell nests with palisading cell layers and a central part of stellate reticulum. (B) Microcystic areas can be seen. (C) Plexiform pattern, showing short strands of cells. (D) Plexiform pattern, showing very thin inter-anastomosing strands in an edematous background.

  • Figure 2.
    Figure 2.

    Continuity of tumor cells with surface epithelium. Three different cases of maxillary ameloblastomas (C and D, same case in different magnifications) showing the surface epithelium (left) communicating with the underlying tumor nests.

  • Figure 3.
    Figure 3.

    (A) Different components can be seen in the same tumor (left plexifom, right acanthomatous). (B) Follicular type maxillary ameloblatoma with evident stellate reticulum and palisading. (C) Follicular maxillary ameloblastoma with central spindle squamous cells. (D) The characteristic palisading cells with reversed polarity surrounding central stellate reticulum.
