ADENOMATOID ODONTOGENIC TUMOR WITH AREAS OF CALCIFYING EPITHELIAL ODONTOGENIC TUMOR

Odontogenic tumors are a group of neoplasms that eventually can present a combination of histopathologic patterns because of their distinct origins. An 18-year-old woman complaining of unerupted teeth attended the clinic. Medical history was noncontributory. Clinical examination showed absence of teeth 12 and 13 in addition to swelling in the alveolar ridge and palate in the corresponding region. Periapical, occlusal, and panoramic radiographs and cone beam computed tomography showed a well-defined radiolucent area with radiopaque foci, associated to unerupted teeth 12 and 13, causing expansion of both vestibular and palatine cortices. Provisional diagnosis was adenomatoid odontogenic tumor, and an excisional biopsy was performed under local anesthesia. Histopathologic findings showed adenomatoid odontogenic tumor with areas of calcifying epithelial odontogenic tumor. The patient is under follow-up in a multidisciplinary team with no signs of recurrence.
