Odontogenic tumor

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 are rare odontogenic lesions , with clinical radiographic and gross features of jaw cysts, which histologicaly show typical ameloblasomatous epithelium lining part of the cyst cavity with or without and /or mural tumor growth. It is usually presented in posterior mandibualar ramus region, while it is rare and atypical in posterior maxillary region. We report a case of 16 year old Kosovar boy, Albanian ethnicity, who presented himself due to a swelling presented in right fronto-lateral maxillary region. Clinical examination revealed a painless swelling extending from right central incisor to first molar same side. Panoramic radiographs disclosed a well corticated unilocular radiolucent lesion approximately 5x5 cm in diameter which inferiorly was in a contact with the roots of the teeth present, and superiorly to the maxillary sinus. Canine impaction of the same site was noted and inside the radiolucency the un-erupted secondary incisor was present. Based on the age of the patient, location of the swelling, clinical and radiographic findings, preoperative diagnose of dentogenous cyst was made, but the UA was also taken into consideration. The patient was treated by surgical enucleation of the lesion and extraction of secondary incisor which was present inside the lesion. The excised lesion was sent for histopatological examination and gauze pack which was put intra-operatively was removed periodically for 3 days from the second day post operation. The histopatological examination finding confirmed for UA mural form. Four year after the operation no signs of relapse are detected. Fronto-lateral maxillary region is considered a rare and atypical location for UA. We emphasize the importance of differential diagnosis of an odontogenic lesion with common clinical and radiological features, since this will impact in treatment planning and follow up. As oral health providers we should be aware of the unilocular radiolucencies as this may be UA
