Papilliferous keratoameloblastoma (PKA) is a rare entity, and not much is known about its clinicodemographic features or biological nature. This review aimed to provide clarity regarding the characterisation of the demographic, clinical, radiological and histopathological features of PKA. Case reports of PKA were identified through a systematic search across multiple databases. The search yielded a total of 10 cases, half of which were of Indian origin. All the cases invariably occurred in the mandibular posterior region and involved the right side; only one case primarily involved the left side of the mandible. PKA should be considered a variant of the conventional ameloblastoma that is towards the more aggressive end of the spectrum. It tends to occur in older individuals (in their fifth decade or older), with a marked propensity to occur in the right mandibular posterior region. Surgical resection with diligent follow-up is warranted in the treatment of PKA.

Papilliferous keratoameloblastoma is an extremely rare variant of ameloblastoma, a benign odontogenic tumor, with only seven cases reported in the English language literature. This variant presents with the metaplastic transformation of stellate reticulum-like cells to the extent of forming papillary structures exhibiting superficial keratinization of varying thickness. This paper describes the pathognomonic macroscopic features of this tumor observed during gross examination under the stereo zoom microscope that differentiate it from the other odontogenic tumors which have not been explored in the previously documented cases.

Ameloblastoma is the most common odontogenic tumor which presents with a variety of histopathological patterns. Among all, papilliferous keratoameloblastoma (PKA) is a very rare type which is characterized by multiple epithelial cysts of varying size, which are lined by non-keratinized papilliferous epithelium which is filled with necrotic desquamated epithelial cells. In this study, we reported PKA with characteristic ameloblastic features in a 65-year-old male patient who presented with a swelling in the right mandibular body region.

Ameloblastoma is true odontogenic tumor of epithelial origin, which is described as locally aggressive with varying chances of recurrence. It is believed to derive from enamel organ, remnants of dental lamina, lining of odontogenic cysts, or basal cells of oral epithelium. Radiologically, it may present as unilocular or multilocular radiolucency commonly.

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.
