Papilliferous Keratoameloblastoma of the Mandible - A Rare Case Report

Abstract

Ameloblastomas are common odontogenic tumours that are benign and locally aggressive. Histopathologically, the tumor exhibits significant diversity with common and rare variants. Here, we report an unusual variant of a common odontogenic tumour in the mandibular posterior region on the right side in a 44-year old male patient. This is the sixth case of Papilliferous Keratoameloblastoma (PKA) to be reported in the English literature till date. More case reports are vital to determine the clinical, radiological, histopathological and behavioural aspects of this extremely rare histological type of ameloblastoma. This tumour awaits re-inclusion as a distinct entity in the future classifications of the WHO Classification of head and neck tumours upon further case accrual.
