Unicystic Ameloblastoma presenting as Dentigerous Cyst
Journal of Contemporary Dentistry, 2013
ABSTRACTUnicystic ameloblastoma refers to those cystic lesions that show clinical, radiographic or gross features of a jaw cyst but on histological 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 behavior of this tumor group was reviewed. Moreover, recurrence of unicystic ameloblastoma may be long delayed and a long-term postoperative follow-up is essential for proper management of these patients. Here, we present a case of unicystic ameloblastoma in a 12-year-old female patient.How to cite this articleBakshi NS, Mukherji S, Chauhan Y. Unicystic Ameloblastoma presenting as Dentigerous Cyst.

Unicystic Ameloblastoma of Mandible with Mural Proliferation: A Case Report
Background: Ameloblastoma is a benign odontogenic neoplasm which frequently affects the mandible. The term ameloblastoma includes several clinicoradiological and histological types. Apart from the most commonly encountered clinicopathologic models, there are few variants, whose biological profile is unknown or not elicited. 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 is believed to be less aggressive. Here we report a distinctive case of mural unicystic ameloblastoma of mandible of a 37 year old male with the radiographic presentation of multilocular radiolucency.
Unicystic ameloblastoma of the mandible-an unusual case report and review of literature
Head Neck …, 2010
Ameloblastoma is a true neoplasm of odontogenic epithelial origin. It is the second most common odontogenic neoplasm, and only odontoma outnumbers it in reported frequency of occurrence. Its incidence, combined with its clinical behavior, makes ameloblastoma the most significant odontogenic neoplasm. Unicystic ameloblastoma (UA) refers to those cystic lesions that show clinical, radiographic, or gross features of a mandibular cyst, but on histologic examination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumor growth. It accounts for 5-15% of all intraosseous ameloblastomas. We report a case of unicystic ameloblastoma in a 30-year-old female, and review the literature.

Maxillofacial images must be examined to find pathologies not identified during clinical examination. Unicystic ameloblastoma (UA) extending to the mandibular body and ramus was neglected on initial panoramic radiographic examination. After orthodontic therapy, a huge lesion was observed clinically and through imaging exams. After the conservative surgery, no recurrence was observed during five years of follow-up. This case emphasized the need for careful evaluation of patient images focusing on the oral diagnosis before any dental treatment planning, including orthodontic therapy.
Unicystic Ameloblastoma as a Differential Diagnosis for Odontogenic Cysts
2014
Unicystic ameloblastoma (UA) is a variant of the solid or multicystic ameloblastoma. Radiographically, though the unilocular appearance is common, it can produce multilocular lesions also. Histologically, the minimum criterion for diagnosing a lesion as UA is the demonstration of a single cystic sac lined by ameloblastomatous epithelium often only in focal areas with or without areas of intraluminal or intramural proliferation or both. The clinical and radiologic presentation of UA can give a confusing picture of odontogenic cysts especially when it is seen in the inter-radicular or periapical area. Also, tooth associated UA may show features similar to dentigerous cyst. Hence histopathologic examination is essential to diagnose such cases. Here we present such a lesion which was initially diagnosed as an odontogenic cyst.
Maxillary unicystic ameloblastoma: A review of the literature
National Journal of Maxillofacial Surgery, 2011
Ameloblastoma is one of the most common types of odontogenic tumor, however, it accounts for only 1% of all oral tumors. [1] It is a benign tumor whose importance lies in its potential to grow to enormous size resulting in bone deformity. The origin of the tumor is thought to be from sources that include residual epithelium of the tooth-forming apparatus, such as the epithelial cell rests of Malassez; epithelium of odontogenic cysts; basal cells of the surface epithelium; epithelium of the enamel organ; and heterotopic epithelium from extraoral sites, such as the pituitary gland. The unicystic type comprises 10%-15% of all ameloblastomas. [2] The unicystic ameloblastoma (UA) was first described as a distinct entity by Robinson and Martinez, although there were several references to these lesions in the earlier literature. It has been termed variously as mural ameloblastoma, intracystic ameloblastoma, cytsogenic ameloblastoma, cystic ameloblastoma, and plexiform UA. [1] The term 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 epithelial lining part of the cyst cavity, with or without luminal and/ or mural tumor growth. This variant is believed to be less aggressive, tends to affect patients at a younger age, and its response to enucleation or curettage is

NON DENTIGEROUS VARIANT UNICYSTIC AMELOBLASTOMA WITH MULTILOCULAR RADIOLUCENCY
sushma bommanavar , 2015
ARTICLE INFO ABSTRACT Unicystic ameloblastoma is a rare, benign tumor of odontogenic epithelium. those cystic lesions that show clinical, radiographic and gross features of a mandibular cyst but on histological examination show a typical ameloblastomatous epithelium lining the cyst cavity with or without luminal and/or mural tumor growth. Most of the cases are associated with This is the dentigerous variant. Sometimes, UA can occur in the ramus area without relationship dentigerous and non dentigerous variant usually demonstrates unilocular radiolucency, although multilocular features also occur. Hence, it is essential that further studies be conducted on non dentigerous with unilocular and multilocular features can alter the prognosis and treatment plan of the lesion. We present a case of unicystic ameloblast-Nondentigerous type in a 38 year old patient showing multilocular radiolucency.

Unicystic ameloblastomas is one of imperturbable jaw tumor. It is a quirky and unique cystic variant of ameloblastoma with clinical and radiological features having kinship with odontogenic cysts of developmental and inflammatory origin and has a favorable prognosis rate. This paper presents a case of a unicystic ameloblastoma in a 24-year-old male in his right angle and ramus of mandible region along with compound odontome in left posterior maxilla.
