The topic Ameloblastoma Odontogenic Tumor you are seeking is a synonym, or alternative name, or is closely related to the medical condition Ameloblastoma.

Quick Summary:

  • An Ameloblastoma is a rare tumor involving excess tissue growths around the jaw. It can occur either in the lower jaw or upper jaw bones. Commonly, the tumor occurs near the un-erupted teeth of the molars
  • Statistically, only 1% of all jaw tumors are Ameloblastomas and in most cases the growth is usually benign (non-cancerous) and non-metastatic (they do not spread). However, these tumors may be locally very aggressive, causing bone destruction at the tumor site
  • The abnormal growths are formed from cell parts that in normal cases would have turned into tooth enamel. If the condition is severe, then the tissue growth may even cause facial deformity
  • A diagnosis of Ameloblastoma is made through radiology imaging and biopsy of the tumor
  • Generally, a surgical removal of the tumor is the preferred treatment method; though, recurrence of Ameloblastoma after surgery is a possibility

There are 3 types of Ameloblastoma and these are:

Multicystic/Conventional Ameloblastoma (also known as Solid Ameloblastoma):

  • A majority of all Ameloblastomas are Multicystic/Conventional Ameloblastomas (over 80%)
  • The tumor is usually seen in middle-aged adults, around the age of 40 years
  • It is more prevalent among African Americans

Unicystic Ameloblastoma (also known as Cystic Ameloblastoma):

  • About 20% of all Ameloblastomas are Unicystic Ameloblastomas
  • It affects men more than women, with 65% of the affected individuals being males
  • It is usually seen in younger individuals with an average age of 25 years
  • A majority of these tumors occur in the lower jaw (over 90%)
  • The prognosis for Unicystic Ameloblastoma is better than Conventional Ameloblastoma, because they are less aggressive in growth
  • However, they can recur after surgery, like Conventional Ameloblastomas

Peripheral Ameloblastoma:

  • Generally, around 2% of Ameloblastomas are of this type
  • Peripheral Ameloblastoma typically affect individuals aged between 40-60 years
  • Both men and women are equally affected
  • The common sites of tumor occurrence include:
    • Soft tissues of jaw
    • Gingiva
    • Buccal mucosa
  • They are generally less aggressive than intraosseous tumors that arise in the bones (Intraosseous Ameloblastoma tumors)
