11/175. Inheritance of Hippel-Lindau disease: a rare case of maxillary bone metastasis.A rare case of familial Hippel-Lindau disease, which is an autosomal dominant disorder with inherited susceptibility to various forms of cancer, is reported in a 46-year-old father and his sons. The father complained of a malignant hypernephroma, which metastasized in the upper jaw 6 months later. As in this patient, renal cell carcinomas are fatal and are exhibited at an early age. Consequentially, patients with familial von hippel-lindau disease exhibiting cases of renal cell carcinoma should be examined very carefully in the head and neck region to detect and treat metastases as early as possible.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
12/175. A review of osteoblastoma and case report of metachronous osteoblastoma and unicystic ameloblastoma.A case is reported of a young woman who, within a 2-year period, was diagnosed with an osteoblastoma at the apex of a maxillary molar and with a plexiform unicystic ameloblastoma in the posterior mandible. Previous cases of osteoblastoma occurring in the jaws are reviewed.- - - - - - - - - - ranking = 2.2901975004882keywords = mandible, jaw (Clic here for more details about this article) |
13/175. Calcifying odontogenic cyst. Report of two cases.Calcifying odontogenic cyst(COC) is an uncommon developmental odontogenic cyst and was first described by Gorlin in 1962. It is considered as extremely rare and accounts for only 1% of the jaw cysts reported. Here, we present two cases of which one occurred in a 32 year old female with a swelling in the lower anterior region crossing the midline and another in a 29 year old male with a swelling in the upper anterior region without crossing the midline. The radiograph revealed a well circumscribed radiolucency in the first case and with some specks of opacities in the second case. It was not associated with any missing or impacted tooth. Histopathological examination was done with hematoxylin and Eosin and in addition it was studied immunohistochemically for cytokeratin. The Classical histological features of lining epithelium in the form of cords, presence of ghost cells and some amount of dentinoid tissue were seen. The nature of COC is controversial. Here we have discussed the controversies regarding COC as well as the various proposed classifications for this lesion. Based on the histopathological findings, the diagnosis was confirmed as calcifying odontogenic cyst. These cases are presented here for its rarity.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
14/175. Urachal carcinoma with metastasis to the maxilla: the first reported case.A case is reported for the first time of a urachal carcinoma with metastasis to the maxilla. The patient presented with a hard swelling along the left upper jaw in the region of 24-27. At the time of onset there were skin changes and signs of metastasis to the brain. The patient died 13 months after the onset of symptoms.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
15/175. Release of extra-articular ankylosis by coronoidectomy and insertion of a free abdominal flap: case report.INTRODUCTION: It is generally agreed that an effective treatment for extra-articular ankylosis may be coronoidectomy and excision of scar tissue. But these conventional procedures have shown a high rate of recurrence of ankylosis due to heterotopic bone and fibrous tissue formation. OBJECTIVE AND PATIENT: We report a case in whom a coronoid osteotomy and insertion of a free abdominal flap was used to treat ankylosis of the mandible following radiotherapy for maxillary cancer. RESULTS: This procedure prevented recurrence of ankylosis by heterotopic bone and fibrous tissue formation. In addition, this flap reduced the risk of postoperative infection and promoted primary healing. CONCLUSION: The procedure, coronoidectomy and insertion of a free flap, was successful because the well-vascularized musculocutaneous flap occupied the dead space, and replaced the shortage of oral mucosa consequently inhibiting the recurrence of extra-articular ankylosis.- - - - - - - - - - ranking = 1.2901975004882keywords = mandible (Clic here for more details about this article) |
16/175. Ameloblastic fibro-odontoma.Ameloblastic fibro-odontoma is a benign, mixed odontogenic tumor most commonly encountered in the mandible of children or teenagers. Treatment of AFO is conservative and requires a long-term follow-up. Although some authors believe that ameloblastic fibroma, ameloblastic fibro-odontoma, and odontomas are extensions of the same disease process, they should be regarded as separate disease entities.- - - - - - - - - - ranking = 1.2901975004882keywords = mandible (Clic here for more details about this article) |
17/175. myxoma of the jaws. Report of three cases.Odontogenic myxoma is a locally aggressive, uncommon benign tumour which arises from mesenchymal tissues normally present in developing teeth. The most frequent locations of odontogenic myxoma are the posterior regions of the mandible, as well as the condylar region. Since odontogenic myxomas are not associated with any specific clinical or radiological sign, a histopathological examination of the specimen is required for confirmation of the primary diagnosis. We report three cases of myxoma diagnosed during the last 18 years. Two of them were located in atypical regions of the mandible and one was located in the maxilla. Presence of a slow-growing swelling associated with expansion of the bone plates raised suspicion of a tumour in two cases, while in the third patient the myxoma was an incidental finding during radiological examination. Due to the unspecific nature of these lesions, in every case a histopathological examination of the surgical specimen was required for diagnostic confirmation. In one of the three reported cases, we shall underline the need to follow a correct diagnostic work-up of all radiolucent lesions of the jaws, in order to avoid contraindicated therapeutic procedures.- - - - - - - - - - ranking = 7.5803950009764keywords = mandible, jaw (Clic here for more details about this article) |
18/175. Odontogenic myxoma containing osteocement-like spheroid bodies: report of a case with an unusual histopathological feature.The odontogenic myxoma is a rare, benign, but locally invasive tumour of the jaws. Radiographically, it is a bone destroying lesion and has ill-defined borders. Histological characteristics are spindle and stellate-shaped tumour cells and a distinct myxomatous stroma. Bony islands that represent residual trabeculae are found scattered throughout the lesion. This report describes a case of odontogenic myxoma that shows diffusely dispersed osteocement-like spherular calcified bodies, unlike residual bone trabeculae, and discusses its differential diagnosis.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
19/175. Tumors of the facial skeleton in children. growth patterns after maxillectomy and mandibulectomy.Thirteen children who had major extirpative surgery of the maxilla or the mandible were followed up an average of five years postoperatively. They ranged in age from three months to eleven years. Facial and oral photographs, cephalograms and cephalometric analysis, and plaster dental models were used to document longitudinal and cross-sectional growth patterns; Our experiences in this limited number of cases has indicated the following: (1) Extensive extirpation of facial bones may be performed in children without significantly jeopardizing function or growth. (2) The roots of healthy teeth may be resected without fear of their noneruption or early loss; loss of sensation with continued viability is the rule. (3) The use of an iliac bone crib with particulate grafts has proved a highly successful means of reconstruction of the mandible in children. (4) Particulate bone has proved to be an effective means of reconstructing large contour defects of the mandible caused by enucleating large tumors in children.- - - - - - - - - - ranking = 3.8705925014646keywords = mandible (Clic here for more details about this article) |
20/175. Multiple cemento-ossifying fibroma: report of an 18-year follow-up.Multiple cemento-ossifying fibroma is a very rare jaw lesion. A unique case is reported involving a 43-year-old Korean woman with rapidly growing, multiple cemento-ossifying fibromas in all four quadrants over an 18-year period which resulted in severe facial deformity and orbital compression.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
