1/182. Intraosseous neurofibroma of the jaws.Two cases of intraosseous neurofibromas of the mandible are presented. Only 25 cases of this tumor have been published previously. Of the present two cases, one was located at the upper border of the mandible, in the left second molar area where the tooth had been extracted 2 years previously. In the second case, the tumor presented itself as a 10 x 2 cm large destruction, mainly following the course of the alveolar nerve from the mandibular foramen to the mental foramen in the right side of the jaw. The mandibular first right molar was missing but the relationship between the extraction of the tooth and the development of the tumor could not be demonstrated. Histologically, the two tumors differed in the way that case 1 showed a conspicuous amount of delicate, wavy fibrils, some of which showed concentric lamellations resembling the pacinian corpuscle but without neurites containing nerve fiber bundles and also demonstrated a slight pleomorphism.- - - - - - - - - - ranking = 1keywords = fibroma (Clic here for more details about this article) |
2/182. Transformation of ameloblastic fibroma to fibrosarcoma.The direct transformation of an ameloblastic fibroma into a fibrosarcoma in a 16-year-old Caucasian male is reported. Although no ameloblastic epithelium was found in the recurrent tumor, the odontogenic origin of the fibrosarcoma was evident. The ameloblastic fibrosarcoma and the fibrosarcoma of identical odontogenic origin represent an entity which should be distinguished from conventional fibrosarcoma as these tumors demonstrate different clinical behaviors.- - - - - - - - - - ranking = 1keywords = fibroma (Clic here for more details about this article) |
3/182. Central fibroma in the ascending ramus of the mandible. Case report.A case of central fibroma involving the mandible in a 58 year old woman is described. There was slight swelling of the left cheek and bone-hard bulging was detected on palpation but the patient had not complained of the swelling. The lesion was removed under general anaesthesia and then examined histopathologically. There was no sign of recurrence eleven months after the operation.- - - - - - - - - - ranking = 1keywords = fibroma (Clic here for more details about this article) |
4/182. Giant central ossifying fibroma of the mandible: report of case.A case is presented of a patient with a giant ossifying fibroma of the mandible that had been diagnosed earlier as fibrous dysplasia. Surgical resection of the tumor and involved bone was chosen as the mode of treatment because of the extent of the lesion and continued infection. Surgeons should be aware that ossifying fibroma is a very distinct possibility in large growing lesions in age groups older than is deemed compatible with fibrous dysplasia.- - - - - - - - - - ranking = 1.2keywords = fibroma (Clic here for more details about this article) |
5/182. Desmoplastic fibroma of the mandible: report of a case.This paper describes a case of desmoplastic fibroma in a 4-year-old patient with a history of a small slowly growing swelling at the right angle of the mandible over a 3-month period. Desmoplastic fibroma was diagnosed on histological and immunohistochemical bases. The lesion responded well to thorough curettage and has not shown signs of recurrence 3 years after the surgical intervention. The clinical picture, the pathology and the management of the case are described, and the differential diagnosis and treatment are discussed.- - - - - - - - - - ranking = 1.2keywords = fibroma (Clic here for more details about this article) |
6/182. Cemento-ossifying fibroma presenting as a mass of the parapharyngeal and masticator space.We report a case of cemento-ossifying fibroma that presented as a large extraosseous mass in the masticator and parapharyngeal space. CT scanning and MR imaging showed a large extraosseous mass with central conglomerated, well-matured ossified nodules and fatty marrow. The central matured ossified nodules were of low density on CT scans and high signal intensity on T1- and T2-weighted MR images. Multiplanar reformatted CT scans revealed the origin of the mass to be at the extraction site of the right lower second molar tooth.- - - - - - - - - - ranking = 1keywords = fibroma (Clic here for more details about this article) |
7/182. Phosphaturic mesenchymal tumor-induced rickets.We describe two prepubertal girls with oncogenic rickets. The first patient, 9 years of age, presented with recent-onset lower-extremity pain. The second girl, presented at 4 years of age following a 9-month period of muscle weakness, bone pain, and poor linear growth. Laboratory analyses in both patients revealed hypophosphatemia and hyperphosphaturia; elevated circulating alkaline phosphatase activity was present in one of them. Radiographic evidence of a generalized rachitic process was evident in both cases. Computerized tomography of the paranasal sinuses and facial bones in patient 1 revealed a small lesion eroding through the inner table of the left mandibular ramus. Microscopic examination of this mass revealed a spindle cell neoplasm with chondroid material, dystrophic calcification, and both osteoclast-like and fibroblast-like cells. Prominent vascularity and marked atypia were present. These features are consistent with a phosphaturic mesenchymal tumor of the mixed connective tissue variant. In the second patient, computerized tomography revealed a lytic lesion located in the right proximal tibia, with histologic features consistent with a phosphaturic mesenchymal tumor of the nonossifying fibroma-like variant. Resection of each tumor resulted in rapid correction of the phosphaturia and healing of the rachitic abnormalities. A careful search for small or occult tumors should be carried out in cases of acquired phosphaturic rickets.- - - - - - - - - - ranking = 0.2keywords = fibroma (Clic here for more details about this article) |

10/182. Peripheral fibroma with calcification--a case report.A female patient aged 10 years reported with an intra oral swelling on the labial aspect of 32 & 33, appearing to originate from the marginal gingiva & interdental papilla. The swelling was pedunculated, mobile, non-tender, firm in consistency with an irregular surface. The colour of the gingiva was normal with slight ulceration. The swelling was excised & diagnosed histopathologically as peripheral cementifying/ossifying fibroma.- - - - - - - - - - ranking = 1keywords = fibroma (Clic here for more details about this article) |
