  • Abstract

Introduction: Unicystic ameloblastoma is an infrequent form of ameloblastoma and refers to cystic lesion that show clinic-radiologic features of an odontogenic cyst but histologically reveal a typical ameloblatomatous epithelium lining part of the cystic cavity.
It often pose a pose a significant diagnostic and therapeutic challenges. Most of the cases involve the posterior region of the mandible. There are few published cases of unicystic ameloblastoma in our setting, hence this report.
Case report: A 17-year old female presented with four years history of painless frontal lower jaw swelling. There was no history of paraesthesia, bleeding, discharge of fluid or pus from this gradually increasing swelling. Physical examination revealed a well circumscribed swelling in the anterior mandible extending from first premolar on the right to the first premolar on the left mandible. There was egg crackling sensation on palpation of the buccal cortical plate. All teeth were firm except the lower right central incisor which showed grade one mobility. Pulp testing done showed that the teeth were viable. Xray showed a well circumscribed radioluscent lesion with cortical rimming suspected to be a dentigerous cyst. Results of routine baseline investigations were essentially normal. The lesion was enucleated via intraoral buccal flap approach and histology confirmed unicystic ameloblastoma.
Conclusion: Unicystic ameloblastoma involving anterior mandible is rare, meticulous observation, high index of suspicion, radiological and histopathological features are essential in making diagnosis.
