1/32. Mandibular mass as the presenting manifestation of IgM myeloma in a 22-year-old man.We report here the youngest known IgM myeloma patient to have presented with a mandibular mass. A 22-year-old Chinese man sought medical attention due to a mass over his right mandible that had been growing progressively for 6 months. A solitary osteolytic lesion in the right mandible was identified radiologically. Incisional biopsy revealed the presence of plasma cells of monoclonal origin, as evidenced by the exclusively positive staining of the kappa light chain. The diagnosis of multiple myeloma with mandibular involvement was confirmed by bone marrow examination. Further tests, including immunoglobulin electrophoresis and assay of the serum levels of kappa and lambda light chains, demonstrated that his myeloma was of the IgM, kappa subtype. The patient achieved a nonsustained partial response to six courses of melphalan and prednisolone therapy and palliative radiotherapy.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/32. Progressive erosive arthropathy with contractures, multicentric osteolysis-like changes, characteristic craniofacial appearance, and dermatological abnormalities: a new syndrome?We report a 27-year-old man with an apparently new syndromic form of progressive erosive arthropathy and contractures of small and large joints associated with mild epiphyseal changes, normal vertebrae, and generalized osteopenia. The patient had a characteristic craniofacial appearance, dermatological abnormalities, and normal intelligence. The head was large with frontal bossing. The face was elongated with malar hypoplasia, thin upper lip, prominent lower jaw, high arched palate, dental malocclusion, and prominent ears with absent ear lobules. Dermatological abnormalities included malar erythema and facial telangiectasia together with multiple nevi and lentigenes all over the body. Pseudorheumatoid arthropathy, spondyloarthropathy, and Borrone dermatocardioskeletal syndrome were considered in the differential diagnosis and were excluded. Also, no similar cases have been found in POSSUM or the london Dysmorphology databases.- - - - - - - - - - ranking = 0.019998478306356keywords = jaw (Clic here for more details about this article) |
3/32. eosinophilic granuloma as a form of inflammatory reaction. A case report.eosinophilic granuloma consists of the proliferation and/or accumulation of langerhans cells in the bones, generally of the cranium and face, as a uni- or multifocal cystic lesion. It is considered to be a localized chronic form of Langerhans cell disease. The most frequent oral location is the posterior part of the mandible, where the bone lesion often gives rise to lesions of the overlying soft tissues. We report a case showing bilateral involvement of the upper jaw and unilateral involvement of the mandible. The eosinophilic granulomas arose in association with odontogenic periapical infectious processes, suggesting that this disorder may be a form of inflammatory response.- - - - - - - - - - ranking = 1.0199984783064keywords = mandible, jaw (Clic here for more details about this article) |
4/32. Anaesthesia of the right lower hemilip as a first manifestation of multiple myeloma. Presentation of a clinical case.multiple myeloma is a malignant proliferation of plasma cells. It may affect any of various bones, causing osteolytic lesions with a characteristic "punched out" radiographic appearance. The commonest symptom is bone pain. One of the most frequent locations is the mandible. Symptoms of multiple myeloma of the mandible include tumefaction, non-specific pain, tooth mobility and sometimes loss, and paraesthesia of the dental nerve. Here we report a case of multiple myeloma of the mandible which was unusual in that the presenting complaint was anaesthesia of the right lower hemilip.- - - - - - - - - - ranking = 1.5keywords = mandible (Clic here for more details about this article) |
5/32. An unusual form of actinomycosis of the mandible with a resultant gross sequester in a 4-year-old child: a case report.Mandibular osteomyelitis due to actinomyces group is considered rare in the pediatric population. The initial complaint of the 4-year-old child described here was increased swelling of his cheek and pain. The patient was managed successfully by surgical treatment with antibiotic therapy.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
6/32. 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 = 2.5399969566127keywords = mandible, jaw (Clic here for more details about this article) |
7/32. growth changes and orthodontic treatment in a patient with condylolysis.A patient with acquired bilateral degeneration of the mandibular condyles was treated orthodontically. The flattening of condyles and the shortening of the ramus began at adolescence. The facial profile changed to a convex type, with a marked mandibular retrognathia and severe Class II malocclusion. The cause seems to be due to a condylolysis of the mandible.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
8/32. Mucinous adenocarcinoma with neuroendocrine differentiation of the mandibular ramus: report of a case.A rare case of mucinous adenocarcinoma with neuroendocrine differentiation of the mandibular ramus is presented. The patient, an 80-year-old man, was referred to our hospital with chief complaint of swelling and pain in the left buccal mucosa. CT and MRI examination showed an osteolytic tumor mass occupying the upper region of the left mandibular ramus. Macroscopically, the excised tumor was a relatively well-defined, solid mass with diffuse bone resorption, measuring 3 cm x 3.2 cm x 3 cm. Microscopical examination showed that the tumor forming glandular structures with abundant mucous production and high cellular atypia. Immunohistochemical studies demonstrated the positive reactivities for pan-keratin, cytokeratin 7, vimentin,alpha-amylase, alpha-smooth muscle actin, neuron-specific enolase, glial fibrillary acid protein, calcitonin, and somatostatin in tumor cells. These findings suggested that the tumor was originated from heterotopic or misplaced salivary gland in the mandible.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
9/32. Glandular odontogenic cyst: case report and review of the literature.Glandular odontogenic cyst (GOC) is a rare developmental cyst of the jaws. It is included in the world health organization (WHO) histologic typing of odontogenic tumors under the terms glandular odontogenic cyst or sialo-odontogenic cyst. The most common site of occurrence is the anterior mandible, and it occurs mostly in middle-aged people. A predilection for men is observed. Clinical findings are not specific, and an asymptomatic swelling is frequently observed. A unilocular or multilocular, well-defined radiolucency is usually seen. The microscopic features of GOC, particularly the morphology of the epithelium, strongly suggest an origin from the remains of dental lamina. GOC has an unpredictable and potentially aggressive nature, which may indicate a high tendency of recurrence. The treatment of choice is still controversial, varying from a curettage to local block excision. A long-term follow-up should be carried out. The aim of this article is to report a case of glandular odontogenic cyst that recurred four times and to emphasize the importance of long-term follow-up. The origin, epidemiology, clinical and radiographic aspects, and treatment of the GOC are also discussed.- - - - - - - - - - ranking = 0.51999847830636keywords = mandible, jaw (Clic here for more details about this article) |
10/32. Tooth development included in the multifocal jaw lesions of Langerhans cell histiocytosis.Many cases demonstrating the oral manifestations of Langerhans cell histiocytosis (LCH) have been reported; however, tooth development in jaw lesions has rarely been mentioned. This paper reports the case of a 3-year-old Japanese girl with LCH suffering from multiple osteolytic lesions of the skull and jaw bones. She was referred to our paediatric clinic because of swelling of the mucogingival folds in the upper and lower primary molar regions. The patient responded well to steroid therapy and the osteolytic lesions resolved. There was an accompanying development of permanent tooth germs included in the lesions. Langerhans cell histiocytosis in children usually has a long-term clinical course and paediatric dentists should be involved with oral health care for affected patients.- - - - - - - - - - ranking = 0.11999086983813keywords = jaw (Clic here for more details about this article) |
