1/13. Periosteal benign osteoblastoma of the mandible. Report of a case and review of the literature pertaining to benign osteoblastic neoplasms of the jaws.A case of periosteal benign osteoblastoma arising in the mandible of a Caucasion male aged 9 years is presented. A review of the literature has produced 24 additional benign osteoblastic neoplasms of the jaws which have been delineated as osteoblastoma or osteoid osteoma. There seems to be a predilection for these lesions to occur in males and in the mandible. Osteoblastomata occur most frequently in patients under 20 years of age whereas osteoid osteomata arise mainly in persons over 25 years of age.- - - - - - - - - - ranking = 1keywords = mandible, jaw (Clic here for more details about this article) |
2/13. Osteoid osteoma of the eminence of the temporomandibular joint.We describe an osteoid osteoma in the articular eminence of the left temporomandibular joint of a 24-year-old woman. This is an uncommon tumour of the jaws, and has not previously been reported in this location. The mass was removed, she made a good recovery, and there are not signs of recurrence four years later.- - - - - - - - - - ranking = 0.017638355968201keywords = jaw (Clic here for more details about this article) |
3/13. Benign osteoblastoma of the mandible. A clinical-pathologic review and report of a case.Benign osteoblastoma is an uncommon, solitary, osteoid and bone-producing tumor which is characterized by prevalent active osteoblasts and rich vascularized delicate fibrous stroma, previously regarded as malignant. The term benign osteoblastoma was recently proposed by different authors to separate this lesion from other solitary benign bone tumors. It most often involves long bones and vertebral column and other bones, and also occurs in jaw bones. There is a close histopathologic similarity between benign osteoblastoma and osteoid osteoma; consequently, much debate about them exists. Benign osteoblastoma has a good prognosis and is best treated by curettage or conservative surgical excision. recurrence is rare. Because of its rarity in jaw bones, one case of benign osteoblastoma of the mandible is reported.- - - - - - - - - - ranking = 0.79511689540223keywords = mandible, jaw (Clic here for more details about this article) |
4/13. Osteoid osteoma in the mandible.A case of osteoid osteoma (OO) in the mandible of 26-year-old female is presented. Her main complaint was intermittent pain during a 3 year period. The panoramic radiograph of the mandible showed diffuse sclerosis including an ill-defined circular radiopacity in the molar region. Computed tomography (CT) revealed an osseous lesion of 10 mm diameter that was located in the cortical bone of the mandible. Bone scintigraphy showed a localized region of high uptake of 99mTc HMDP. The lesion was diagnosed as an OO by histopathological examination of the surgical specimen and CT findings. Since radiological appearance has very significant meaning in the differentiation of an OO from other bone forming tumors, CT is the method of choice when the main symptom is pain and the conventional radiography was not informative.- - - - - - - - - - ranking = 1.0637762568522keywords = mandible (Clic here for more details about this article) |
5/13. Central giant cell granuloma and fibrous dysplasia occurring in the same jaw.Fibrous dysplasia (FD) is a developmental tumor like condition that is characterized by replacement of normal bone by an excessive proliferation of cellular fibrous connective tissue intermixed with irregular bony trabeculae. Central giant cell granuloma (CGCG) is described as a benign lesion affecting the mandible and maxilla that consists of a massive fibrohistiocytic proliferation with numerous heavily hemosiderin-laden multinucleate-giant cells. A 20 year old woman present at the Department of oral medicine, dentistry School, Tehran University of Medical Sciences with a slowly growing non painful swelling of the right mandible for one year. Our differential diagnosis was osteoma, osteoid osteoma and Fd. The histological feature reveal Central giant cell granuloma fibrous dysplasia. Central giant cell granuloma and fibrous dysplasia occurring in the same jaw is rarely reported in the literatures.- - - - - - - - - - ranking = 0.39212785322734keywords = mandible, jaw (Clic here for more details about this article) |
6/13. osteoblastoma of the maxilla and mandible: a report of 24 cases, review of the literature, and discussion of its relationship to osteoid osteoma of the jaws.osteoblastoma is a benign neoplasm of bone characterized by a proliferation of osteoblasts forming bone trabeculae set in a vascularized fibrous connective tissue stroma. We report 24 examples of this neoplasm arising in the maxilla and mandible and compare the clinical and radiographic characteristics of this neoplasm to 53 previously reported examples of osteoblastoma and osteoid osteoma in the jaws. Our results reveal more females reported in the new examples of osteoblastoma than in the previously reported examples of osteoblastoma and osteoid osteoma. This raises the overall female percentage from 47.2% to 58.4%. In addition, significantly fewer patients reported pain, tenderness, and discomfort associated with their neoplasms than in previously reported cases. When all cases are combined, a predominant trend is observed whereby osteoblastoma occurs predominantly on the left side of the posterior mandible and is associated with pain, tenderness, and discomfort. We also provide a rationale for use of the term "osteoblastoma" for any benign osteoblastic neoplasm arising in the jaws.- - - - - - - - - - ranking = 1.0176383559682keywords = mandible, jaw (Clic here for more details about this article) |
7/13. Atypical multiple benign osteoblastomas accompanied by simple bone cysts. A case report.A case of atypical benign osteoblastomas occurring at multiple sites in the maxilla and mandible of a 38-year-old woman, in association with simple bone cysts, is described. The tumors produced hazy or ground-glass-like semiradiolucent lesions with well-defined or poorly-defined margins on conventional radiographs. Histologically, the lesions were characterized by a proliferation of plump osteoblast-like cells forming trabeculae of osteoid and immature bone in a well-vascularized stroma. In addition, simple bone cysts associated with a radiolucent-radiopaque lesion consisting of lamellar bone and loose connective tissue were found next to one of the tumours. Possible pathogenesis of the tumours and cysts is discussed.- - - - - - - - - - ranking = 0.15196803669317keywords = mandible (Clic here for more details about this article) |
8/13. Benign cementoblastoma: review of the literature and report of a case at an unusual location.Benign cementoblastoma is a rare odontogenic tumour localized in the jaws of young people. Benign cementoblastoma has characteristic radiologic and microscopic features and it appears to be fused to the tooth roots. The most important differential diagnosis is-with a benign osteoblastoma. The tumor should be enucleated and the teeth extracted. This case represents only the third reported case of a benign cementoblastoma associated with a third molar.- - - - - - - - - - ranking = 0.017638355968201keywords = jaw (Clic here for more details about this article) |
9/13. Benign osteoblastoma of the mandible.Benign osteoblastoma is a rare osteoblastic tumour with osteoid and bone deposition. A rapidly growing osteoblastoma involving the area of the mandibular first and second molar of a 20-year-old female is described. Investigation of the collagenous components of the tumour by immunofluorescence was suggestive of a normal collagen synthesis by the tumour osteoblasts. The lesion is discussed with particular emphasis on its differential diagnosis and matrix constituents.- - - - - - - - - - ranking = 0.60787214677266keywords = mandible (Clic here for more details about this article) |
10/13. osteoblastoma of the jaws: current concepts and differential diagnosis.A review of previously documented cases of osteoblastoma has been presented and an additional case has been reported. Although the clinical and histologic distinctions for fibrous-osseous lesions cover a wide spectrum, several means of differentiating osteoblastoma from similar lesions have been discussed. A larger series of cases will allow us to further delineate clinical, histologic, and biologic variables of osteoblastoma.- - - - - - - - - - ranking = 0.070553423872804keywords = jaw (Clic here for more details about this article) |
