Unicystic plexiform ameloblastoma: An insight for pediatric dentists

Abstract

Ameloblastomas have been categorized broadly into three biologic variants: cystic (unicystic), solid, and peripheral. The term plexiform unicystic ameloblastoma refers to a pattern of epithelial proliferation that has been described in cystic lesions of the jaws. Although the histology suggests that cystic ameloblastomas follow a biologically low-grade course, recent evidence suggests that they may often behave clinically as biologically aggressive tumors. This is supported by the high incidence of cortical perforation, tooth resorption, lesion size, bony destruction, and a high rate of recurrence after simple enucleation. This article tries to provide an insight for pediatric dentists regarding this biologically distinct entity. A literature review on the topic has been added along with a case report highlighting the state-of-the-art approach and management of such ameloblastomas, in pediatric patients.

Unusual imaging appearance of unicystic ameloblastoma

“…The literature indicates that the cystic variant is biologically less aggressive and has a better response to enucleation or curettage than the solid ameloblastoma. [1] Multicystic ameloblastoma is the most common variety and represents 86% of cases. Peripheral tumors are odontogenic tumors, with the histological characteristics of intraosseous ameloblastoma that occur solely in the soft tissues covering the tooth-bearing parts of the jaws.…”

Ameloblastoma: Uma análise abrangente de diagnóstico, opções de tratamento e suas correlações clínicas

“…Histologicamente, o ameloblastoma se compõe de epitélio odontogênico agrupado em ilhas (folicular) ou em cordas amarradas (plexiforme) separadas por tecido conectivo. As duas formas, folicular e plexiforme, podem ainda coexistir no mesmo tumor (Yavagal, et al, 2009).…”
