Adenomatoid odontogenic tumor associated with odontoma: a case report and critical review of the literature

We describe a case of adenomatoid odontogenic tumor (AOT) associated with odontoma occurring in the posterior mandible of a 32-year-old man. Although calcifications are commonly found in the AOT, the presence of rudimentary dental structures is a very rare phenomenon. Cases with similar aspects have been described as ameloblastic dentinoma, ameloblastic odontoma, adenoameloblastic odontoma and AOT associated with odontoma. After a careful analysis of the literature we describe the clinical aspects of this tumor. Further case reports and surveys of odontogenic tumors are necessary to define whether AOT associated with odontoma is a variant of AOT or a distinct clinicopathologic condition.
