1/44. Intraosseous squamous cell carcinoma arising in association with a squamous odontogenic tumour of the mandible.We report a rare occurrence of intraosseous squamous cell carcinoma (SCC) arising in association with a squamous odontogenic tumour (SOT), which had not previously been documented in the literature. A 53-year-old man had, for 5 years, a well-demarcated radiolucency attached to the impacted third molar of the mandible. The enucleated specimen had a characteristic pattern of SOT, but in which a few epithelial islands showed atypical features suggestive of SCC. Intense p53-, proliferating cell nuclear antigen- and Ki-67-positive cells were detected in carcinoma areas. Within 2 months, aggressive bone destruction showing typical findings of intraosseous SCC appeared. The present tumour is presumably a malignant variant of SOT.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/44. odontoma-producing intraosseous calcifying odontogenic cyst: case report.The present report describes a case of odontoma-producing intraosseous calcifying odontogenic cyst in a 36-year-old Black male in the right mandibular bicuspid region. The lesion involved an unerupted permanent canine, which was displaced to the mandible base and a calcified mass that was later recognized as an odontoma. The lesion was surgically removed.- - - - - - - - - - ranking = 0.2keywords = mandible (Clic here for more details about this article) |
3/44. Invading basal cell carcinoma of the jaw: an under-evaluated complex entity.Basal cell carcinoma (BCC) is a locally invasive neoplasm, rarely metastatic, yet capable of significant local destruction and disfigurement. Invasion into the bone is uncommon and only a few cases of invasion into facial bones, but never to the mandible or maxilla, have been described. We report three patients with BCC lesions invading their jaws, as a consequence of which either their mandible or maxilla had to be partially resected. This resulted in facial mutilation which required comprehensive multi-disciplinary therapy to restore function and esthetics. Such therapy requires a combination of modalities offered by both plastic and maxillofacial surgeons, as well as oral and dental rehabilitators.- - - - - - - - - - ranking = 0.47575957316205keywords = mandible, jaw (Clic here for more details about this article) |
4/44. 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 = 0.015151914632411keywords = jaw (Clic here for more details about this article) |
5/44. A case of an ameloblastic fibro-odontoma arising from a calcifying odontogenic cyst.This case report describes an ameloblastic fibro-odontoma arising from a calcifying odontogenic cyst (COC) in the mandible of a twenty-three-year old male. The patient was referred to the Department of Oral Surgery, tokyo Dental College, on March 30th, 2000, complaining of a painful swelling, which had appeared three weeks earlier on his left mandibular molar region. In a pathological view, the lesion was a round cyst the size of a chicken-egg, dark red in color, and surrounded by a thick membrane. The cyst had an epithelium of varying thickness which included many ghost cells and an enamel-like structure on the inside, and a thick wall of connective tissue with an ameloblastic fibro-odontoma on the outside. enamel organ-like epithelial islands were structured radially in the form of strands with immature dentin. Cytokeratin 19 was strongly immunoreactive in the epithelium of the lesion; osteopontin and osteocalcin reacted in the mesenchymal cells and weakly in the epithelial element of this tumor.- - - - - - - - - - ranking = 0.2keywords = mandible (Clic here for more details about this article) |
6/44. Multiple congenital epulis of the alveolar ridge and tongue.Congenital granular cell tumor, also known as congenital epulis, is a very rare lesion seen in newborns. The typical presentation is a solitary nodule occurring on the gingiva of the anterior alveolar ridge of either jaw. Multiple-site involvement is seen very seldom but has been noted on the same or different alveolar ridges. However, tongue involvement is exceptional, and there have been only three cases reported involving both the alveolus and the tongue. A female newborn with multiple congenital epulis on the mandibular alveolar ridge and tongue is presented, and her preferred treatment and histopathological diagnosis are discussed.- - - - - - - - - - ranking = 0.015151914632411keywords = jaw (Clic here for more details about this article) |
7/44. Ameloblastic carcinoma: report of an aggressive case with multiple bony metastases.Ameloblastic carcinoma is a rare primary tumor of the maxillofacial skeleton with a distinct predilection for the mandible. These lesions may initially show histologic features of ameloblastoma that dedifferentiate over time. Other ameloblastic carcinomas initially present with morphologic features suggestive of ameloblastoma with areas of epithelial dedifferentiation. We herein report a rare case of aggressive ameloblastic carcinoma in a 22-year-old white man who developed widespread bony metastases and expired 4 years after initial diagnosis.- - - - - - - - - - ranking = 0.2keywords = mandible (Clic here for more details about this article) |
8/44. Malignant haemangio endothelioma (angiosarcoma) concomitant presentation in the mandible and occiput--a case report.A case of angiosarcoma presenting simultaneously in the mandible and occiput is presented. The mandibular swelling was preceded by toothache for which the patient had tooth extraction, after which the rate of growth increased tremendously. It was not possible to determine without doubt which lesion presented first. The need to evaluate and investigate all cases of jaw swelling that require tooth extraction is emphasised. Angiosarcoma being a haemorrhagic lesion could be complicated life threatening haemorrhage, if a tooth related to it is extracted, as was experienced on incisional biopsy of this lesion. The procedure was accompanied by torrential bleeding which was only controlled after external carotid artery ligation. This, to our knowledge, is the first reported case of angiosarcoma occurring simultaneously in the mandible and occipital bones.- - - - - - - - - - ranking = 1.2151519146324keywords = mandible, jaw (Clic here for more details about this article) |
9/44. Giant ossifying fibroma. Case report on a bimaxillary presentation.Ossifying fibroma is a slow-growing, benign neoplasm, but some lesions behave aggressively, reaching massive proportions, thus demanding special treatment. The following case report holds particular interest, because of the simultaneous occurrence of an active ossifying-cementifying fibroma in the maxilla and mandible with the maxillary lesion attaining enormous size.- - - - - - - - - - ranking = 0.2keywords = mandible (Clic here for more details about this article) |
10/44. Bilateral multiple pulmonary metastases in a patient with double advanced cancer of the head and neck.A case of advanced gingival cancer is described. The cancer invaded into the mandible and skin of the cheek and was associated with cervical lymph node metastases, mediastinal lymph node metastases, and bilateral multiple pulmonary metastases. The patient received neoadjuvant chemoradiotherapy and local immunotherapy, followed by curative surgery for the primary and neck lesions. Histopathological examination of the primary cancer and the upper and middle cervical nodes (n = 7) indicated a diagnosis of squamous cell carcinoma. Sections of the lower cervical nodes (n = 5) revealed well-differentiated thyroid carcinoma, suggesting that the mediastinal and pulmonary lesions were of thyroid origin. After total thyroidectomy and mediastinal dissection followed by treatment with radioiodine, the multiple pulmonary nodules disappeared. There has been no evidence of recurrent tumour for 5 years.- - - - - - - - - - ranking = 0.2keywords = mandible (Clic here for more details about this article) |
