1/20. Burkitt's lymphoma presenting as mandibular swelling--report of a case and review of publications.Burkitt's lymphoma in a 4-year-old Chinese boy presented with acute mandibular swelling but no associated systemic disturbance. A review of published reports shows that the diagnosis should be suspected in jaw lesions with no obvious cause.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
2/20. osteosarcoma of the jaw. The Chaim Sheba Medical Center experience.OBJECTIVE: The purpose of this article is to present 14 cases of osteosarcoma of the jaw treated at our medical center from 1989 to 1998. These cases are discussed in the light of a comprehensive review of 774 cases reported in the English literature over the past 3 decades. Differences between osteosarcoma of the jaws and osteosarcoma of the long bones are examined. SUBJECTS AND methods: The patients ranged in age from 8 to 78 years, the mean age being 33 years. Each patient had a histopathologically established diagnosis of osteosarcoma of the jaw. Records were reviewed for epidemiologic data, treatment modalities, and survival. RESULTS: Of the 14 patients, 6 (42%) had tumors in the mandible and 8 (58%) had tumors in the maxilla. Of the mandibular tumors, 5 occurred in the body of the mandible; all maxillary tumors originated in the alveolar ridge and involved the maxillary sinus. The chief complaint was an intraoral or extraoral painless swelling. Histopathologic types included chondroblastic, osteoblastic, fibroblastic, and malignant fibrous histiocytoma-like. Pathologic grade was determined to be high (3 or 4) in 13 cases and low (1) in only 1 mandibular case. All patients underwent surgical resection and immediate reconstruction. Adjuvant therapy included postoperative radiation (5 patients), postoperative chemotherapy (2 patients), and preoperative chemotherapy and postoperative radiation (1 patient). CONCLUSIONS: The results of the present study support the literature indicating that osteosarcoma of the jaw differs from osteosarcoma of the long bones in its biological behavior even though they have the same histologic appearance. Because of differences in tumor characteristics, the introduction of chemotherapy did not dramatically alter the prognosis of osteosarcoma of the jaw. early diagnosis and radical surgery are the keys to high survival rates.- - - - - - - - - - ranking = 10.607336024883keywords = jaw, mandible (Clic here for more details about this article) |
3/20. Odontogenic myxoma of the maxilla: a report of two pediatric cases.Myxomas are benign, slow growing neoplasms derived from mesenchyme. While these tumors most frequently occur in the myocardium, the other sites most commonly affected are the maxilla and mandible. Nevertheless, myxoma is a very uncommon lesion of the midface, particularly in the pediatric population. We present two reports of infant children with midfacial myxomas. The clinical features, radiographic evaluation and treatment of these cases will be presented.- - - - - - - - - - ranking = 0.80366801244157keywords = mandible (Clic here for more details about this article) |
4/20. Clinical and radiological findings in Gardner's syndrome: a case report and follow-up study.Gardner's syndrome is characterized by colorectal adenomas, multiple osteomas, especially of the skull, and various soft-tissue tumours. The disease is inherited as an autosomal dominant disorder and all untreated patients will develop colorectal adenocarcinomas. Since the clinical and radiological stigmas in the maxillofacial area, such as exosteal and endosteal osteomas, skin cysts, atypical skin pigmentation and abnormal dental findings or radiopaque lesions can precede the often symptomless adenomas for many years, dentists, maxillofacial surgeons and radiologists should be familiar with the manifestations of this disease. A case is reported to illustrate the dentist's role in the diagnosis of Gardner's syndrome. In a follow-up study of 11 patients with colorectal adenomas, the typical triad of features of Gardner's syndrome was found in eight. In six patients, bony changes were demonstrated by panoramic radiography. It is proposed that radiography of the jaws may serve as a valuable tool for the early detection of carriers of Gardner's syndrome.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
5/20. Arteriovenous malformation of the maxillary sinus and mandible: a case report.Vascular tumors are rarely encountered in the paranasal sinuses. When they do arise there, they can be life-threatening because of the risk of bleeding. Embolization alone and in combination with surgical resection has been the mainstay of treatment. We report the case of a prepubertal girl who experienced two recurrences of arteriovenous malformation, one in the maxillary sinus and the other in the mandible. To our knowledge, this is the first report in the literature of recurrences arising in these two locations.- - - - - - - - - - ranking = 4.0183400622079keywords = mandible (Clic here for more details about this article) |
6/20. osteosarcoma of the jaws in children.Two cases of osteosarcoma of the jaws in children are reported. One patient was a 13-year-old girl whose first symptoms included nasal and maxillary sinus congestion, followed by epistaxis. She was found to have chondroblastic osteosarcoma extending through the left maxillary alveolar process and sinus. Following surgery and chemotherapy, the patient has been free of disease for 7 years. The second patient, an 8-year-old boy, was diagnosed with juxtacortical (parosteal) osteosarcoma of the mandible, which is a less aggressive variant of the neoplasm. It is believed that this is the youngest patient reported to date with juxtacortical osteosarcoma of the jaws. He was treated by block resection of the right side of the mandible and is free of disease 3(1/2) years later.- - - - - - - - - - ranking = 7.6073360248831keywords = jaw, mandible (Clic here for more details about this article) |
7/20. osteosarcoma of the maxilla and the maxillary sinus: a case report.osteosarcoma of the jawbones is a rare malignant mesenchymal neoplasm with the tendency for new bone being directly formed by the tumor cells. Clinically, the tumor may be central or peripheral--periosteal--and histologically can be divided into three subtypes: osteoblastic, fibroblastic, and chondroblastic. This report presents a case of a central osteoblastic osteosarcoma of the left maxillary tuberosity and maxillary sinus. Problems related to definitive diagnosis and therapy are described and discussed.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
8/20. Recurrent calcifying odontogenic cyst involving the maxillary sinus.The calcifying odontogenic cyst is an uncommon lesion that occurs in both jaws, however involvement of the maxillary sinus is rare. The accepted mode of treatment is enucleation with curettage since it is generally believed that recurrence following such treatment is extremely rare. Of the reported cases of recurrent calcifying odontogenic cysts, none have involved the maxillary sinus. This report is of a large recurrent calcifying odontogenic cyst involving the maxillary sinus, eroding the orbital floor as well as anterior and medial walls of the maxillary sinus and displacing an impacted upper canine into the nasal cavity, in a 45-year-old male patient, 8 years after the initial enucleation.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
9/20. Metastatic tumours in upper maxillary bone of esophageal adenocarcinoma. A case report.Metastases in the oral cavity are rare lesions which represent approximately 1% of all malignant neoplasms in the oral cavity. Oral metastases are located in the mandible 80-90% on average, the maxilla location being rarer. Metastases in mouth soft tissue are also rare, and within these it is on the gums where they more frequently occur. Primary tumours which metastasize to mouth are most commonly: lung, breast and kidney. Oral cavity metastases appear as a result of distant disease spreading and show wrong prognosis, with short survival. Here we present a clinical case of a patient diagnosed with esophagus adenocarcinoma which presented metastasis in upper-left maxillary bone.- - - - - - - - - - ranking = 0.80366801244157keywords = mandible (Clic here for more details about this article) |
10/20. Sinonasal undifferentiated carcinoma of the maxillary sinus.We describe the case of a 43-year-old man who was referred to our dental school"s acute care clinic with pain and swelling of presumed dental origin in the left maxillary quadrant. Radiographic examination revealed extensive dental decay and periodontal disease. On questioning, the patient admitted to paresthesia of recent onset. paresthesia associated with pain or swelling of the jaws is an ominous sign that should alert the clinician to the possibility of an underlying aggressive neoplasm. In this case, biopsy of the lesion confirmed that the patient had a rare malignant tumour of maxillary sinus origin, a sinonasal undifferentiated carcinoma.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
