1/57. Malignant spindle cell tumor arising in the mandible of a patient with florid osseous dysplasia.Florid osseous dysplasia is a non-neoplastic condition of the alveolar processes of the jaws characterized by the replacement of multiple foci of bone by fibrous connective tissue, accompanied by gradual deposition of cementum, bone, or both. The lesions are not associated with inflammatory diseases of the dental pulp or periodontal tissues. In fully developed florid osseous dysplasia, there are multiple lobulated masses in the alveolar bone bilaterally in the mandible and sometimes in the maxilla. This is the first report of a malignancy originating within the jaws of a patient with florid osseous dysplasia. A spindle cell malignancy was diagnosed in the mandible of a 54-year-old black woman whose jaw was affected by florid osseous dysplasia bilaterally. Despite extensive surgery and radiotherapy, the patient died 20 months after diagnosis of the malignancy.- - - - - - - - - - ranking = 1keywords = mandible, jaw (Clic here for more details about this article) |
2/57. 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 = 0.73868867925099keywords = mandible (Clic here for more details about this article) |
3/57. Fibro-osseous lesion of the mandible mimicking chronic osteomyelitis.An account is given of the clinical, radiologic, and pathologic, features of a special form of fibro-osseous lesion of the mandible. The material consists of fifteen cases (eleven females and four males). Two cases are described in detail. Together with Case 1, a probably unique series of radiographic pictures is presented, showing the development of the disease.- - - - - - - - - - ranking = 0.73868867925099keywords = mandible (Clic here for more details about this article) |
4/57. Florid osseous dysplasia of the mandible: report of a case.In 1986, a 60-year-old African American woman visited the Marquette University School of dentistry with a complaint of a vague, dull pain in her lower left quadrant. tooth No. 19 was extracted 10 years earlier because of extensive decay, and tooth No. 18 had received root canal therapy. A panoramic radiograph revealed the presence of ill-defined, multilocular, mixed (radiopaque-radiolucent) lesions present throughout the lower jaw. She was treated with antibiotics and scheduled for follow-up visits. When the symptoms persisted, tooth No. 18 was re-treated with root canal therapy and a representative biopsy was taken from the left mandibular area. The biopsy showed the presence of chronic osteomyelitis. The patient was treated with antibiotics and was scheduled for periodic check-up visits. In February 1995, she returned with the same symptoms in the left mandible. A panoramic radiograph showed persistence of the mixed radiopaque-radiolucent lesions throughout her mandible; however, the mass on the left side was more radiopaque and had assumed a "cotton wool" appearance. tooth No. 18 was extracted and a biopsy was taken from the area. After correlating the clinical behavior, radiographic appearance, and histopathologic features, a diagnosis of florid osseous dysplasia with osteitis was made. This case represents a classic example of the difficulty in diagnosing fibro-osseous lesions using radiographic interpretation alone and the need to correlate the clinical, radiographic, and histopathologic features to reach a diagnosis. Additionally, the present case clearly shows treatment problems of an otherwise self-limiting condition when secondary involvement with osteomyelitis is also present. A brief description of the conditions that were included in the differential diagnosis and their management is presented.- - - - - - - - - - ranking = 0.92445345868334keywords = mandible, jaw, lower (Clic here for more details about this article) |
5/57. Fibrous dysplasia arising from the calcaneus.A case of an 18-year-old woman with fibrous dysplasia arising in the calcaneus, which is extremely rare, is reported, with the emphasis placed on differential diagnosis from low-grade central osteosarcoma. She had a severe pain in her left ankle after sprain. Plain radiographs showed a radiolucent lesion measuring 6.3 x 2.5 cm with a sclerotic margin in the left calcaneus. CT scans showed a well-defined lytic lesion with disruption of the lateral cortex and an ossification or calcification in its center. On MR imaging, the lesion had isointensities and high intensities on T1 and T2 weighted images, respectively, but its central portions showed lower intensities both on T1 and T2 weighted images. The lesion was enhanced with gadolinium except for the central portions. The specimen obtained by open biopsy consisted of fibrous tissue and foci of irregular woven bone. None of the nuclear atypia, mitoses, longitudinal stream of bone or invasive nature of growth was detected. The diagnosis of fibrous dysplasia was histologically made. The lesion was curetted and packed with autogenous bone chips. No evidence of recurrence was noted postoperatively.- - - - - - - - - - ranking = 8.4590974604866E-5keywords = lower (Clic here for more details about this article) |
6/57. Juvenile ossifying fibroma of the mandible. An 8 year radiological follow-up.An 8-year follow-up of a juvenile ossifying fibroma in the left mandible of a 4-year-old boy is presented. The case demonstrated initial lack of radiological evidence of demarcation and subsequent eccentric enlargement, selective tooth displacement and a multilocular appearance in areas of active growth. An aneurysmal bone cyst and a decrease in the bone content was present in the excision specimen.- - - - - - - - - - ranking = 0.73868867925099keywords = mandible (Clic here for more details about this article) |
7/57. Gigantiform cementoma: clinicopathologic presentation of 3 cases.Gigantiform cementoma is a rare, benign fibro-cemento-osseous disease of the jaws, seen most frequently in young girls. Radiographically, it typically presents as multiquadrant, expansile, mixed radiolucent-opaque lesions that cross the midlines of the jaws. Although cases with a familial pattern are noted in a few publications, sporadic cases have been reported without a family history. The term gigantiform cementoma has been used interchangeably with designations of other fibro-osseous entities, yet its application should be restricted by the criteria defined herein. In this article, we report 3 cases of gigantiform cementoma. Clinical, radiographic, and microscopic features of these lesions are presented, along with criteria to differentiate gigantiform cementoma from other fibro-osseous diseases of the jaws. A possible pathogenetic mechanism and treatment recommendations are discussed.- - - - - - - - - - ranking = 0.11357358489881keywords = jaw (Clic here for more details about this article) |
8/57. 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 = 0.18937389913929keywords = jaw, lower (Clic here for more details about this article) |
9/57. cherubism in siblings: a case report.cherubism is a non-neoplastic bone disease characterized by clinically evident bilateral, painless enlargements of the jaws that are said to give the patient a cherubic appearance. cherubism may appear in solitary cases or in many members of the same family, often in multiple generations. On radiography, the lesions exhibit bilateral multilocular radiolucent areas. Histopathologic evaluation reveals proliferating fibrous connective tissue containing numerous multinucleated giant cells. Since the first description of this condition in 1933, almost 200 cases have been reported. We describe cherubism in 2 siblings and briefly review the literature on this subject.- - - - - - - - - - ranking = 0.037857861632936keywords = jaw (Clic here for more details about this article) |
10/57. Fibrous dysplasia of mandible with chronic osteomyelitis in a child: report of one case.We report here a 6-year-old girl with fibrous dysplasia (FD) of the mandibular bone. She had a growing mass with local pain over right chin after a severe trauma, which was thought to be chronic osteomyelitis (OM). After failure of antibiotic treatment, malignant bone tumor was suspected from imaging studies including magnetic resonance imaging (MRI). FD of the mandible with chronic OM was confirmed one year after its onset by repeated biopsy performed at our hospital. Causes of delayed diagnosis may include (1) FD of the mandibular bone and chronic OM have similar characteristics clinically and radiographically, (2) the previous biopsy was not performed at appropriate site, and (3) failure to include fibrous dysplasia in the differential diagnosis. In this report, we also review the features in radiology and MRI of OM and FD, which may help differentiate the diagnosis. When a patient with mandibular FD has acute symptoms, the possibility of superimposed OM or malignant change should be considered.- - - - - - - - - - ranking = 0.73868867925099keywords = mandible (Clic here for more details about this article) |
