The growth had expanded the palatal, alveolar and buccal aspect to such an extent that the overlying mucosa had indentation marks from the lower teeth causing discomfort to the patient during speech and mastication [Figure 1].

The orthopantomography (OPG) revealed [Figure 2] a radiolucent lesion with irregular borders located between the apices of the left maxillary lateral incisor and the left maxillary second premolar.

Under premedication (i.e. injection atropine, 0.6 mg IM, 60 min before surgery and injection diazepam 5-10 mg IM) and local anesthesia, an adequate window was created and the tumor mass was enucleated along with the enclosed 24 tooth [Figures 4 and 5].
