Summary
Adenomatoid odontogenic tumor (AOT) is a rare, benign jaw tumor. This case highlights typical AOT features in a young adult, emphasizing its distinct characteristics and excellent prognosis with complete removal.
Area of Science:
- Oral Pathology
- Odontogenic Tumors
- Maxillofacial Surgery
Background:
- Adenomatoid odontogenic tumor (AOT) is a benign odontogenic neoplasm with a 2.2-7.1% prevalence.
- Often termed the "two-thirds tumor," AOT typically affects the maxilla, young individuals, and unerupted teeth in approximately two-thirds of cases.
- Maxillary canine impaction is a common association.
Observation:
- AOT presents as a slow-growing, painless swelling.
- Radiographically, it can mimic various odontogenic cysts and tumors, necessitating careful differential diagnosis.
- This report details a characteristic case in a 22-year-old male.
Findings:
- The case exhibited classic AOT presentation.
- Differential diagnosis is crucial, including dentigerous cysts, ameloblastomas, and other odontogenic lesions.
- Histopathological examination confirms the diagnosis.
Implications:
- Conservative surgical enucleation is the primary treatment modality for AOT.
- The recurrence rate is exceptionally low (0.2%) with complete excision.
- Complete surgical removal in toto ensures an excellent long-term prognosis.
