Hemangiomatous ameloblastoma: Case report with a brief review

Papilliferous Keratoameloblastoma: Systematic review

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.

Vascularized ameloblastoma: A case report and clinicopathologic review of 18 cases from the literature

The notable features of ameloblastoma do not typically include prominent vascularity. However, on rare occasions, vascular ameloblastoma has been described under a variety of names. We present a case of vascularized ameloblastoma that had a bloody return on fine-needle aspiration. The English language literature contains a total of 16 reports (18 cases) of vascular or hemangioma-like ameloblastoma. We reviewed the clinical, pathologic, and radiographic features of the 19 cases, but further study and more cases are needed. The recognition of this variation of ameloblastoma is important for clinicians to note that fine-needle aspiration with a bloody return does not exclude ameloblastoma from diagnostic consideration. We suggest the term vascularized ameloblastoma to avoid any suggestion of a vascular neoplasm.
