Unicystic Ameloblastoma in 6-Year-Old Child and Its Significance

ABSTRACT Ameloblastoma is a true neoplasm of odontogenic epithelial origin. Unicystic ameloblastoma 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 to 15% of all intraosseous ameloblastomas. They believed to be less aggressive and respond more favorably to conservative excision than the solid or multicystic ameloblastomas. We report a case of unicystic ameloblastoma of the anterior part of the mandible that was treated by enucleation and use of Cornoy's solution under suspicion of an odontogenic cyst. The nature of the lesion became evident only when the enucleated material was available for histologic examination. With this report, we illustrate the importance and complexity of a differential diagnosis of lesions with a cystic aspect in the anterior region of the mandible, among them are dentigerous cyst, odontogenic keratocysts, adenomatoid odontogenic and unicystic ameloblastoma.

Ameloblastoma is a neoplasm that originates from odontogenic epithelium. It is the second most common neoplasm of the oral cavity. Unicystic ameloblastomas refer 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 part of the cyst cavity, with or without luminal and/ or mural growth. Even though the lesion is not that aggressive as the solid ameloblastoma, an accurate diagnosis should be made. This lesion needs to be treated more aggressively than any other periapical lesions.

ABSTRACT Unicystic 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 article Bakshi NS, Mukherji S, Chauhan Y. Unicystic Ameloblastoma presenting as Dentigerous Cyst.

Unusual Case Report

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. Among these types, unicystic ameloblastoma is the least encountered variant of the ameloblastoma. 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. 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 postoperative followup is essential for proper management of these patients. Here we are presenting a case of unicystic ameloblastoma in an 18-year-old female patient.

Pathologic Classification

Abstract Context.—Cystic lesions of the pancreas are being recognized with increasing frequency and have become a more common finding in clinical practice because of the widespread use of advanced imaging modalities and the sharp drop in the mortality rate of pancreatic surgery. Consequently, in the past 2 decades, the nature of many cystic tumors in this organ has been better characterized, and significant developments have taken place in the classification and in our understanding of pancreatic cystic lesions. Objective.—To provide an overview of the current concepts in classification, differential diagnosis, and clinical/biologic behavior of pancreatic cystic tumors. Data Sources.—The authors' personal experience, based on institutional and consultation materials, combined with an analysis of the literature. Conclusions.—In contrast to solid tumors, most of which are invasive ductal adenocarcinomas with dismal prognosis, cystic lesions of the pancreas are often either benign or low-grade indolent neoplasia. However, those that are mucinous, namely, intraductal papillary mucinous neoplasms and mucinous cystic neoplasms, constitute an important category because they have well-established malignant potential, representing an adenoma-carcinoma sequence. Those that are nonmucinous such as serous tumors, congenital cysts, lymphoepithelial cysts, and squamoid cyst of pancreatic ducts have no malignant potential. Only rare nonmucinous cystic tumors that occur as a result of degenerative/necrotic changes in otherwise solid neoplasia, such as cystic ductal adenocarcinomas, cystic pancreatic endocrine neoplasia, and solid-pseudopapillary neoplasm, are also malignant and have variable degrees of aggressiveness.

This report demonstrates a simple endodontic solution to an interdisciplinary case of a patient with multiple gene deficiencies. An adolescent patient presented with an impacted premolar that could not be extracted due to high-risk conditions. A suspicious degree of radiolucency around the crown was clinically diagnosed as dentigerous cyst. The treatment dilemma and implementation are discussed. This case report offers a different treatment option for impacted teeth when significant differential diagnosis of a pericoronal lesion dictates treatment.
