title: Maxillary unicystic ameloblastoma: a case report.
abstract: BACKGROUND
  Ameloblastoma is a benign epithelial odontogenic tumor. It is often aggressive and destructive, with the capacity to attain great size, erode bone and invade adjacent structures. Unicystic ameloblastoma is a rare odontogenic lesion, with clinical, radiographic and gross features of jaw cysts. The lesion histologically shows typical ameloblastomatous epithelium lining part of the cyst cavity with or without and/or mural tumor growth. Unicystic ameloblastoma usually presents in posterior mandibular ramus region, while it is rare and atypical in posterior maxillary region. .
  
  
  METHODS
  We report a case of 16 year old Kosovar male, Albanian ethnicity, who presented with a swelling located in right maxillary region. Clinical examination revealed a painless swelling extending from the maxillary right central incisor to the maxillary right first molar tooth. Panoramic radiograph disclosed a well corticated unilocular radiolucent lesion approximately 5 × 5 cm in diameter which was in contact with the roots of the teeth present inferiorly and with the maxillary sinus superiorly. Maxillary right canine impaction was noted and unerupted lateral incisor tooth was present inside the radiolucency. Preoperative diagnosis of the lesion was made as dentigerous cyst based on the age of the patient, location of the swelling, clinical and radiographic findings, but the unicystic ameloblastoma was also taken into consideration. The patient was treated by surgical enucleation of the lesion and extraction of lateral incisor tooth which was present inside the lesion. The histopathological examination of the lesion revealed confirmed finding for unicystic ameloblastoma mural form. No recurrence was observed in 1 year follow-up.
  
  
  CONCLUSIONS
  Maxillary region is considered a rare and atypical location for unicystic ameloblastoma. We emphasize the importance of differential diagnosis of an odontogenic lesion with common clinical and radiological features that will impact the treatment planning and follow up. As oral health providers we should be aware that the unilocular radiolucencies may be unicystic ameloblastoma.
