Aggressive granular cell ameloblastoma arising from radicular cyst: a case report of an unusual variant and a public health concern

Background: Ameloblastoma is the second most common odontogenic tumor and categorized into various clinical and histopathological types. They are found exclusively in the mandibular posterior region, mainly between third and fifth decades of age. However, granular cell ameloblastoma is a unique and rare histologic variant of unicystic/multicystic ameloblastoma. Although it is rare, it has greater recurrence potential and chances of malignant potential.
