Unicystic Ameloblastoma Associated with Primary Mandibular Second Molar: A Case Report

Unicystic ameloblastoma is a rare, benign, locally invasive odontogenic neoplasm of young age that shows clinical, radiographic, or gross features of an odontogenic cyst but histologically shows typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumor growth.

To report a case of an asymptomatic unicystic ameloblastoma in a 12-year-old child, along with its management and follow-up.

A 12-year-old boy presented with swelling with respect to the left body of the mandible. The orthopantomogram (OPG) and computed tomography scan revealed a large unilocular radiolucency in the left mandible associated with the primary second mandibular molar. Complete enucleation of the cyst and extraction of the associated primary teeth and underlying permanent teeth were done under general anesthesia. Carnoy's solution was applied in the bone cavity for 3 minutes with cotton applicators. Postoperative healing was uneventful. Prosthetic rehabilitation was done during the follow-up period.

Unicystic ameloblastoma is rarely seen in younger children, so a pediatric dentist must be cautious while diagnosing an intraoral swelling. Timely intervention and conservative surgical treatment, along with a proper follow-up, improved the treatment outcome and prevented potential complications in the future.

This report highlights the salient features of unicystic ameloblastoma to be able to accurately diagnose and manage the lesion.
