• odontoameloblastoma
  21 May 2008

  Odontoameloblastomas are extremely rare oral tumors. For the cases that have been described, they happen to occur in the mandible of young patients.
  In contrast to AF, they are destructive lesions on radiographs and have calcifying components.
  Histologically, these tumors have ameloblastomatous component as wlee as odontoma-like components.
  Biologically, they tend to behave like ameloblastoma and characterized by multiple recurrence and local aggression.

• ameloblastic fibrosarcoma
  10 April 2006

  Ameloblastic fibrosarcoma is a rare tumor and only the mesenchymal component shows features of malignancy but the epithelial compoment remains bland.
  These tumors can occur de novo but can also be associated with recurrent ameloblastic fibroma or ameoloblastic fibroodontoma. There are usually no difficulties in recognizing the anaplastic features of the mesenchymal component.
  It should be noted that in some cases, particularly those with multiple recurrences, the mesenchymal component can (...)
