1/16. A case of Burkitt's lymphoma that presented initially with resorption of alveolar bone.A 16-year-old male was evaluated for a 1-month history of alveolar bone resorption, which had been treated with endodontics by a neighborhood dentist. Intraoral examination showed slight gingival swelling and teeth mobility. However, no tumor mass was seen. The panoramic image showed resorption of alveolar bone and loss of teeth lamina dura. Because he complained of general fatigue, he was introduced to the internist. Biopsies of gingiva and bone marrow aspiration revealed a massive proliferation of lymphoblasts expressing CD10, 19, 20 and hla-dr antigens on the surface. Their karyotypes were abnormal; 46, XY, t (8;14) (q24;q32). Accordingly, he was diagnosed as Burkitt's lymphoma, and received intensive chemotherapy which relieved his symptoms and decreased his tumor. However, his disease soon became refractory to chemotherapy, and he died 11 weeks after the onset.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/16. 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 = 0.16666666666667keywords = alveolar (Clic here for more details about this article) |
3/16. Unusual presentation of mastoid eosinophilic granuloma in a young patient.eosinophilic granuloma is a well-recognized form of Langerhans cell histiocytosis, most commonly involving the skull bones, usually with an excellent prognosis. Recurrent and difficult to recognize osteolytic lesions of the skull are encountered only rarely. A patient with recurrent eosinophilic granuloma of the skull is reported. In spite of appropriate multimodality treatment, there were several recurrences, most recently with involvement of the mastoid process. Imaging studies revealed extensive involvement of surrounding structures with expansion of the tumor into the middle cranial fossa and slight pressure on the antero-medial portion of the temporal lobe of the brain. Despite extensive involvement, the patient had no complaints. Because of the rarity of such silent and unpredictable lesions, a systematic approach with regular CT and MRI follow-up is suggested.- - - - - - - - - - ranking = 0.00085161418382031keywords = process (Clic here for more details about this article) |
4/16. cherubism and its charlatans.cherubism is a rare hereditary condition characterised by progressive cystic proliferation of the mandible and maxilla in childhood, followed by post-pubertal involution of the process and jaw remodelling in adulthood. Its name is derived from the cherubic appearance that results from the jaw hypertrophy. Here, we present the case of a young boy with cherubism, in the context of his pedigree, to illustrate the clinical characteristics and their variable expression. We also seek to distinguish cherubism from central giant cell granuloma and giant cell tumour of the jaws, with which it holds a false synonymity.- - - - - - - - - - ranking = 0.00085161418382031keywords = process (Clic here for more details about this article) |
5/16. Concomitant focal fibrocartilaginous dysplasia of the tibia and eosinophilic granuloma of the jaw in a child.This 2-year-old child presented with concomitant eosinophilic granuloma of the lower jaw and focal fibrocartilaginous dysplasia of the right tibia. Her eosinophilic granuloma was diagnosed on the basis of the clinical picture, imaging studies and the characteristic histologic appearance. Focal fibrocartilaginous dysplasia was revealed incidentally during the eosinophilic granuloma staging process. After chemotherapy, all signs of eosinophilic granuloma subsided, but focal fibrocartilaginous dysplasia remained without signs of clinical or radiographic progression. The importance of differentiating these two conditions is stressed in order to avoid ineffective and inappropriate treatment of focal fibrocartilaginous dysplasia.- - - - - - - - - - ranking = 0.00085161418382031keywords = process (Clic here for more details about this article) |
6/16. Calcifying epithelial odontogenic (Pindborg) tumor. A clinical case.Calcifying epithelial odontogenic tumor (CEOT), Pindborg tumor, is a rare benign odontogenic neoplasm representing about 0.4-3% of all odontogenic tumors. This tumor more frequently affects adults in an age range of 20-60 years, with a peak of incidence between 40 and 60 years. About 190 cases of CEOT have been reported in the dental literature. Fifty-two percent of cases of CEOT is associated with a tooth impacted and/or displaced by the tumor. The primary CEOT has a recurrence rate of 10-15%, after total excision, and its malignant transformation is a very rare occurrence. The authors report a case of primary intra-osseous CEOT, embedding the mandibular right second molar, in a 24 year-old male. Radiographs showed a well-defined unilocular osteolytic lesion, swelling and reabsorbing the mandible and displacing the inferior alveolar nerve. It was possible to perform conservative surgical treatment consisting of the enucleation of the tumor together with a portion of tumor-free bone cavity margin and the debridement of the inferior alveolar neuro-vascular bundle, which was surrounded by a tumor capsule-like structure. The postoperative histological examination of the tumor revealed typical benign features. The differential diagnosis and work-up of the tumor treatment are discussed in relation with its histological typing and localization in the jaws.- - - - - - - - - - ranking = 0.33333333333333keywords = alveolar (Clic here for more details about this article) |
7/16. Ossifying fibroma of the upper jaw: report of a case and review of the literature.A number of processes generically referred to as benign fibroosseous lesions comprise different disorders such as fibrous dysplasia, sclerotizing osteomyelitis and ossifying or cementing fibroma. These processes are all characterized by the existence of a vascular fibroblastic stroma, with the production of a calcified matrix ranging from bone to cementum. Ossifying fibroma involves slow-evolving growth with deforming swelling generally arising in the mandible, with possible early dental displacement. From the radiological perspective the disorder generally manifests as a well defined and delimited, unilocular radiotransparency, as a radiotransparent image with central opacifications, or as multilocular transparencies. The lesions exceptionally can be radiopaque. We present the case of a 22-year-old male presenting for evaluation of a three-month, asymptomatic tumor mass in the anterior sector of the upper jaw. Radiologically, the lesion appeared as a radiotransparent zone surrounded by a poorly delimited sclerotic halo. The definitive diagnosis following surgical resection of the lesion was ossifying fibroma. The case is discussed, and a review is provided of the literature on the subject.- - - - - - - - - - ranking = 0.0017032283676406keywords = process (Clic here for more details about this article) |
8/16. Clinical observations of odontomas in Japanese children: 39 cases including one recurrent case.Retrospective investigations of odontomas in Japanese children and one recurrent case were carried out. Thirty-nine cases of odontoma in 38 children were treated in the Paediatric dentistry Clinic of Niigata University Dental Hospital between September 1979 and December 2002. The patients consisted of 23 males and 15 females and their ages ranged from 1 year 2 months to 14 years old. The chief complaints were delayed tooth eruption in 19 cases (five: primary teeth, 14: permanent teeth), retention of primary teeth in 11, incidentally found on the radiographic examination in eight cases, and swelling of the jaw in one case. Thirty-four cases (87%) were associated with tooth eruption disturbances. The most frequently affected region was the maxillary anterior region. Treatment consisted of surgical removal of odontomas in all cases, after which if the impacted teeth did not erupt, exposure of the crown and/or orthodontic traction was performed. Pathological diagnoses were compound odontoma in 30 cases, complex odontoma (n = 7), and compound and complex odontoma (n = 2). A retrospective study of the radiographs revealed the developing process of odontomas in four cases and odontoma disturbed tooth eruption since the early uncalcified developing stage. A recurrent case was a boy aged 6 years 5 months in whom the first surgical removal of odontoma was performed at the age of 1 year 8 months. recurrence of an odontoma is very rare, but in very young children odontomas are in the early developing stages, containing uncalcified portions, so it is important to perform periodical observations until the succedaneous teeth erupt.- - - - - - - - - - ranking = 0.00085161418382031keywords = process (Clic here for more details about this article) |
9/16. multiple myeloma of the periodontium. A case report.Multiple periodontal lesions were the presenting features leading to a diagnosis of multiple myeloma in a 38-year-old male. Ulceration and bleeding from a rapidly growing retromolar myelomatous mass, multiple foci of alveolar bone destruction and cortical expansion together with multifocal skeletal destruction were the hallmarks of the neoplastic process. radiotherapy and chemotherapy brought a substantial, but temporary, remission with improvement of the periodontal condition.
