Adenomatoid Odontogenic Tumor with Radicular

Adenomatoid odontogenic tumor is a benign, slow growing lesion. It is a relatively uncommon lesion which mainly affects females in their second decade of life, exhibiting predilection for the anterior region of the maxilla. The lesion is usually associated with the crown of an unerupted tooth, most commonly the maxillary canine. We present a case of adenomatoid odontogenic tumor associated with a dentigerous cyst affecting the left maxillary region in a 18-year-old female, who presented with gingival swelling. Histopathologic examination showed round to plump to spindle-shaped epithelial cells forming aggregates with minimal connective tissue, and cuboidal or low columnar cells forming glandular duct-like structures. The diagnosis of adenomatoid odontogenic tumor should be considered in a case with a corticated radiolucency in the anterior jaw, especially in teens and young adults. The patient has shown no signs of recurrence after eleven months of follow up period.
