Granular Cell Variant of Unicystic Ameloblastoma of Anterior Mandible: a Case Report and an Updated Literature Review

Unicystic ameloblastoma (UA) is an uncommon odontogenic tumor derived from odontogenic apparatus and comprises 6% of all ameloblastomas. We report a case of a forty-nine-year-old male presented with a chief complaint of bleeding from gums, pain, and difficulty in eating of one-year duration. The lesion was excised and diagnosed as unicystic ameloblastoma (type 1.2.3) with extensive granular cell change in all components. Granular cell variant of unicystic ameloblastoma appears to be a rare variant of unicystic ameloblastoma with only five satisfactory cases reported till date. As reported, this variant may show late recurrence as solid ameloblastoma hence a strict close follow-up is warranted.
