  • Men and women ages 40 - 60 years
  • Soft tissue of posterior gingiva and ascending ramus
  • True peripheral variants may be less aggressive than intraosseous tumors
  • Cross sectional imaging, rather than plain film imaging, is imperative to exclude an intraosseous ameloblastoma with a prominent extraosseous component.
    • Gingival lesions with radiographic ‘cupping’ of the bone may not be peripheral ameloblastoma, but a very peripherally placed intraosseous ameloblastoma that has perforated (Head Neck Pathol 2010;4:192)
