Unicystic ameloblastoma of the mandible

Abstract

Unicystic ameloblastoma refers to those cystic lesions that show clinical, radiographic or gross features of a jaw cyst but on histologic examination show a typical ameloblastomatous epithelium lining the cyst cavity, with or without luminal and/or mural tumor proliferation unicystic ameloblastoma is a less encountered variant of the ameloblastoma and believed to be less aggressive. As this tumor shows considerable similarities with dentigerous cysts, both clinically and radiographically the biologic behaviour of this tumor group was reviewed. Moreover, recurrence of unicystic ameloblastoma may be long delayed and a long-term post-operative follow up is essential for proper management of these patients. Here we are presenting a case of unicystic ameloblastoma in a 18 year old female patient.

Enucleation Followed by Open Packing of Iodoform Gauze in Mandibular Unicystic Ameloblastoma: A Case Report

“…On the other hand, recent advances in the understanding of the biological features of ameloblastomas have lead to more successful conservative surgical treatments [16] [17]. Unicystic ameloblastoma diagnosed as microscopic sub-group A and B can be treated conservatively like careful enucleation with/without adjunctive therapy but if cortical perforation was present than it behaves like solid ameloblastoma and managed accordingly [1] [4]. A general agreement was made to eradicate these lesions completely with the help of aggressive surgical approach like resection with or without continuity defects.…”

“…Unicystic ameloblastoma diagnosed as sub-group A and B can be treated conservatively like careful enucleation with/without adjunctive therapy, whereas sub group C and D required radical resection, as for a solid or multicystic ameloblastoma [4] [5]. According to recent literatures, if cortical perforation was present then it behaves like solid ameloblastoma and managed accordingly [1]. Aggressive surgical approach like resection with or without continuity defects may cause mutilation.…”

“…Ameloblastomas are benign odontogenic tumors having potential to grow into enormous size with resulting bone deformity [1]. Clinically ameloblastoma was classified into four sub-groups like solid or multicystic, unicystic, desmoplastic and extra-osseous or peripheral [2].…”

Prevalence of jaw lesions in Bagalkot population a clinical and radiographic study

“…No date is available concerning prevalence and incidence. 6 Of the 6 cases of Ameloblastoma (0.14%), 4 (0.19%) were present in males and 2 (0.13%) in females. Of the 7 cases of KCOT (0.17%), 5 (0.24%) were in male and 2 (0.13%) were in females.…”

Ameloblastoma of the Mandible: A Case Report with Review of Literature

“…1 Their name implies a resemblance to cells of the enamel-forming organ. It represents about 1% of all oral ectodermal tumors and 9% of odontogenic tumors.…”
