Mural Adenomatoid Odontogenic Tumor in the Mandible - A Rare Case

Adenomatoid odontogenic tumor is a uncommon benign hamartomatous lesion of odontogenic origin, which affects young individuals, with a female predilection and mainly occurs in the second decade. It is considered as a hamartoma because of its limited size, due to minimal growth potential, and lack of recurrence. The epithelial lining of the odontogenic cyst may transform into an odontogenic neoplasm-like ameloblastoma or Adenomatoid odontogenic tumor. Such combined lesions are rare and must be carefully diagnosed by an oral pathologist so that optimum treatment needs of the patient can be met. We are here reporting a case of cyst associated with Adenomatoid odontogenic tumor in a 17 year old female patient in the mandible, which was clinically diagnosed as dentigerous cyst or unilocular ameloblastoma. This report of a cyst in the mandible associated with an Adenomatoid odontogenic tumor is extremely rare. Combined lesions of such variety are uncommon and hence the importance of grossing and histopathology in such cases should not be undermined.
