BACKGROUND Jaw complications, including osteoradionecrosis, are significant sequelae of radiation therapy (RT) for oral cancers. This study identifies the impact of patient, tumor, and treatment characteristics on the development of jaw complications in patients treated with RT. METHODS The Surveillance, Epidemiology, and End Results (SEER)-Medicare database was used to identify patients trea...

PURPOSE The purpose of the article is to present 8 new cases of metastatic tumors occurring in the jawbones, their clinical features , diagnostic workup and management. PATIENTS AND METHODS The records of 8 patients with metastatic jaw lesions were reviewed. Demographic data, presenting symptoms, primary tumor site, radiographic findings, bone scintigraphy , histopathology and clinical manage...

Keratocystic odontogenic tumor (KCOT) is a benign intraosseous neoplasm of the jaw. Involvement of the maxillary sinus is an unusual presentation. We present the case of a 23-year-old man with extensive KCOT and impacted third molar in the right maxillary sinus. The clinical, radiological, and histological features of this tumor and its surgical management are discussed.

Clinical presentation in extranodal and nodal sites of rapidly expanding masses in high-risk populations suggests Burkitt lymphoma (BL). Most patients present with advanced disease because of the rapid rate of tumor growth. BL cells have a remarkably short doubling time. Children in equatorial Africa and Papua New Guinea have endemic BL and present with facial tumors in the jaw or orbit, abdomi...

Mandibular swellings can be caused by many benign lesions of odontogenic or non-odontogenic origin. The most common tumor of odontogenic origin is ameloblastoma which develops from epithelial cellular elements and dental tissues in various stages of development. It is a benign, yet locally aggressive intraosseous odontogenic tumor occurring most often in the mandible followed by maxilla (1). It...

introduction: primary gastric lymphoma (pgl) is a rare tumor, whose differential diagnosis may become complicated without precise immunohistochemistry (ihc) and genetic analysis. case presentation: a 33-year-old woman presented with gastric cancer and had undergone gastrectomy without precise ihc and staging in another center. inappropriate ihc after surgery showed diffuse large b-cell lymphoma...

Background: One of the most significant factors in the success of dental implant procedures, can be mentioned by the quality and quantity of jaw bone. The occurrence of some problems such as trauma, infection, pathological lesions and the long-term absence of teeth in patients, it causes irregularities in the jaw bone and can get bone resorption. Sever defects after trauma or tumor resection ne...

central granular cell odontogenic tumor) cgcot) of the jaw is an exceedingly rare benign odontogenic neoplasm with 35 reported cases in the literature. among these, very few studies have focused on the cone-beam ct features of cgcot. here, we report a case of an asymptomatic cgcot in a 16-year-old girl and focus on the cone-beam ct features. only 36 cases of this lesion, including this one, hav...

osteoma is a benign, slow-growing osteogenic tumor that sometimes arises from the craniomaxillofacial region, such as the sinus, temporal or jaw bones. osteoma consists of compact or cancellous bone that may be peripheral, central or extraskeletal type. peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass. peripheral osteoma of the mandible...

Case Presentation: A 33-year-old woman presented with gastric cancer and had undergone gastrectomy without precise IHC and staging in another center.
