One of the most rapidly growing areas of dentistry of both interest and need is maxillofacial prosthetics. Malignant tumours of the upper gum and hard palate account for 1-5% of malignant neoplasms of the oral cavity; two thirds of the lesions which involve these areas are squamous cell carcinomas. Most of these carcinomas are diagnosed late, when they invade the underlying bone. The procedures...

Introduction Juvenile nasopharyngeal angiofibroma is a rare benign neoplasm in the nasopharynx. The tumor tends to be locally aggressive and is typically seen in adolescent boys. Extranasopharyngeal angiofibromas have been reported sporadically in the literature. They most commonly originate from the maxillary sinus. Objectives A 26-year-old woman was referred to our clinic with intermittent ep...

Based on the histopathologic origin, malignant maxillary neoplasms may share some clinical characteristics but have different biological behavior, treatments, and prognoses. The aim of the present study was to explore the association between CT characteristics and tissue origin of primary maxillary cancer (MC). A retrospective review of CT findings was performed in patients diagnosed with MC be...

There are few studies on oral-maxillary lesions in children and adolescents, and reports on malignant neoplasms are scarce. Comparison of available data is difficult due to the different criteria and racial-ethnic origin of the populations in each study. The aim of this work was to perform a retrospective study of malignant oral neoplasms in patients aged up to 20 years diagnosed at a center sp...

Reprint requests to: Dr. Yu-Chang Lee Department of Radiology E-Da Hospital/I-Shou University. No.1, Yi Da Road, Jiau-shu Tsuen, Yan-Chau, Kaohsiung 824, Taiwan, R.O.C. Schwannomas are common neoplasms in the head and neck region, but of these tumors only less than 4% was found in sinonasal location in the reported literature. Most of the reported cases are found in the maxillary or ethmoid sin...

Odontomas are the most common type of odontogenic tumors and account for approximately 22% of maxillary odontogenic tumors [1-3]. They are considered to be developmental anomalies rather than true neoplasms [4]. They are generally asymptomatic [1]. The term odontoma was coined by Paul Broca in 1867. The World Health Organization (WHO) 2005 has categorized odontomas based on the histopathologica...

Oral squamous cell carcinoma (SCC) represents 90% to 95% of all malignant neoplasms of the oral cavity. It is classically regarded as an adult disease entity and has a high correlation with alcohol and tobacco consumption.1 Oral SCC occurs in several well established intraoral sites, including the floor of mouth, tongue (most common), gingiva, lips, and buccal mucosa. It might also present in t...

UNLABELLED The adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin, composed of odontogenic epithelium and characterized by slow but progressive growth. We report a rare case of AOT in an 18-year-old, who presented with a palpable bony-hard swelling in the anterior maxillary region. The tumor was radiographically well-defined, and exhibited unilocular radiolucency. Hi...

Non-Hodgkin’s Lymphoma is a group of neoplasms that originate from the cells of the lymphoreticular system. In 40% of cases, it arises from extranodal sites. The nasal cavities and paranasal sinuses are rarely affected by primary Non hodgkin’s lymphoma. We report the case of a 60-year-old man admitted for Non-Hodgkin’s Lymphoma of maxillary sinus. CT scan demonstrated an extensive lesion destro...
