A case of large adenomatoid odontogenic tumor in the posterior region of the mandible showing root resorption

Abstract

Introduction: Adenomatoid odontogenic tumor (AOT) is a rare tumor of epithelial origin, and usually presents as a unilocular radiolucency in the maxillary anterior region in adolescent females. Observation: A 31-year-old Japanese male, having a large adenomatoid odontogenic tumor from the right molar region to the left anterior region of the mandible showing root resorption of the neighboring teeth, was presented to the hospital. The lesion was totally resected under general anesthesia. Commentary: AOT may cause displacement of the neighboring teeth. But root resorption is a very rare finding. AOTs are relatively small in size. Conclusion: The patient was under follow-up and had not shown any signs of recurrence 12 months after surgery.
