The nasopalatine duct cyst is the most common non-odontogenic developmental cysts. Nasopalatine duct cyst also termed as incisive canal cyst, arises from embryologic remnants of nasopalatine duct. Most of these cysts develop in the midline of anterior maxilla near the incisive foramen. This article reports a case and review of literature with respect to epidemiology, etiology, clinical presentation, radiographic and pathological findings, treatment and recurrence rates.
The MDM2 overexpression noticed in plexiform ameloblastoma, follicular ameloblastoma with granular cell changes and acanthomatous ameloblastoma when compared to simple unicystic and desmoplastic ameloblastoma suggest a relatively enhanced proliferative phenotype of these solid multicystic variants of ameloblastomas. On overall comparison, higher expression was noted in ameloblastomas when compared to AOT. This indicates differences in the aggressive nature between these two groups of odontogenic tumors favoring the perception of a greater aggressive nature of ameloblastomas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
