1/10. Metastatic transitional cell carcinoma of the urinary bladder presenting as a mandibular gingival swelling.Oral cavity metastases mostly originate from the breasts, lungs, or kidneys. Transitional cell carcinoma (TCC), the most frequent malignant tumor of the urinary bladder, rarely metastasizes to the jaws. To the best of our knowledge, only 8 cases of bladder carcinoma have been reported in the English literature to metastasize to the jawbones. A new case of mandibular metastasis of urinary bladder TCC with extension to the gingiva is presented in a 64-year-old white man. The patient was referred for a periodontal infection of the upper right first molar. The clinical examination also showed a gingival swelling located in the lower left premolar region with a hypoasthesia of the left side of the lower lip. The gingival mass was biopsied, and the microscopy showed a mandibular metastatic TCC of the urinary bladder extending to the gingiva. Periodontists should be aware that, although gingival metastases are rare, when they occur they may mimic other local benign pathological conditions.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/10. Inferior alveolar nerve paresthesia caused by endodontic pathosis: a case report and review of the literature.Sensory disturbances such as anesthesia, hypoesthesia, hyperesthesia, and paresthesia may be present in the oral cavity, stemming from many local and systemic factors. paresthesia of the inferior alveolar nerve is quite rare because of the unique anatomy of this nerve. Among other effects, periapical lesions can damage the nerve, resulting in paresthesia of its innervated area. Only a few cases of paresthesia caused by these lesions are reported in the literature. In this report we present a case of paresthesia of the right inferior alveolar nerve; discuss the anatomy, pathobiology, and etiology; and suggest that a periapical lesion affecting the lower right second molar (No. 31) may have been the cause. The routine x-rays (intraoral and panorex) and the axial and cross-sectional tomographs of the mandible by means of computed tomography contribute to making this case a good example of nerve injury.- - - - - - - - - - ranking = 13.415419567389keywords = oral cavity, cavity (Clic here for more details about this article) |
3/10. Multimodality management of a giant cell tumor arising in the proximal sacrum: case report.STUDY DESIGN: Descriptive. OBJECTIVE: To outline a novel multimodality approach for a difficult surgical resection of a giant cell tumor in the cephalad portion of the sacrum. SUMMARY OF BACKGROUND DATA: giant cell tumors of the sacrum are rare primary bone tumors. Recent reports have demonstrated diminished giant cell tumor recurrence with cryosurgery by using a "direct pour" technique with liquid nitrogen. Although successful in decreasing tumor recurrence, this technique is accompanied by a 4%-8% rate of skin necrosis and high rates of pathologic fracture. The authors describe resection and a novel, controlled method of argon-based cryotherapy (followed by a unique pelvic reconstruction) for a large, difficult giant cell tumor of the sacrum. methods: A 29-year-old woman presented with complaints of right foot drop and decreased sensation of the right buttock, posterior thigh, posterior calf, and lateral aspect of the right foot. Radiographic evaluation revealed a mass in the right sacrum; histologic examination of CT-guided biopsy revealed a giant cell tumor. A combined anterior abdominal and posterior sacral approach was performed, the tumor was resected, and the margin of the cavity was treated with controlled argon-based cryotherapy. The combination of thermocouples, electromyographic monitoring, and rapid freeze-thaw cycles allowed a controlled ablation of the tumor margin while ensuring that surrounding structures, such as the rectal wall, sacral nerves, and gluteal muscles, were not damaged. Posterior spinal fusion L4 to sacrum, posterior spinal instrumentation L4 to pelvis, and allograft reconstruction of the right sacrum were performed. RESULTS: The patient recovered well without skin necrosis or pathologic fracture. Urinary and fecal continence were preserved. At the 20-month follow-up the patient has no evidence of local tumor recurrence and is fully ambulatory without a brace or narcotic medication. CONCLUSION: A novel multimodality approach, consisting of resection, controlled cryosurgery, and a unique lumbopelvic reconstruction, was safe and successful in managing a challenging proximal sacral giant cell tumor. Twenty months after surgery the patient has excellent bowel and bladder control, no tumor recurrence, and functional ambulation without a brace or pain.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
4/10. Ciguatera neurotoxin poisoning mimicking burning mouth syndrome.burning mouth syndrome is a condition in which the patient perceives a sensation of intraoral burning, typically of the anterior tongue. This article presents a case report of a patient presenting for orofacial pain evaluation in whom ciguatera neurotoxin poisoning is diagnosed. The clinician should be aware of neurotoxin poisoning as a possible cause of symptoms of burning mouth, especially among patients who have recently traveled to a tropical area. Recognition of this condition in this case highlights the need for a detailed and accurate patient history.- - - - - - - - - - ranking = 18.680311861779keywords = mouth (Clic here for more details about this article) |
5/10. Facial numbness in a man with inguinal and retroperitoneal masses.BACKGROUND: A 37-year-old Brazilian man was admitted to massachusetts General Hospital for evaluation of left-sided facial numbness, left-sided ataxia, dizziness, and vertigo. Seven weeks prior to admission, he reported numbness of the left oral cavity and tongue after a dental procedure. Three weeks prior to presentation, he developed left-sided incoordination with dizziness and vertigo. One week later, he noticed difficulty using a box cutter at work and presented to the emergency department for evaluation. A CT scan without contrast revealed no abnormalities and he was discharged home. Three days prior to admission, the patient developed diplopia. Cranial MRI revealed a 1.6 cm irregular enhancing mass in the left middle cerebellar peduncle. neurologic examination was significant for diminished sensation over the left face to pinprick, left-sided dysmetria, and mild lateral instability of the trunk while walking. INVESTIGATIONS: MRI, lumbar puncture, CT scans of the abdomen and pelvis, needle biopsy of the lymph node, and paraneoplastic antibodies. diagnosis: Possible paraneoplastic demyelination. MANAGEMENT: orchiectomy, adjuvant radiation, and corticosteroids.- - - - - - - - - - ranking = 13.415419567389keywords = oral cavity, cavity (Clic here for more details about this article) |
6/10. Orofacial injury in a Brazilian professional basketball player: case report.The frequency of dental trauma has increased among children and athletes of all ages who play contact sports. This kind of trauma may result in irreversible damage to the patient. The aim of this report is to present a case of an orofacial trauma involving a professional basketball player who was elbowed by another player. The athlete reported loss of sensitivity in three teeth and computerized tomography showed fractures in three points of the malar bone. After the incident and dental follow-up, the player was made aware of the need to wear a mouthguard.- - - - - - - - - - ranking = 3.1133853102965keywords = mouth (Clic here for more details about this article) |
7/10. Cheiro-oral syndrome with bilateral oral involvement: a study of pontine lesions by high-resolution magnetic resonance imaging.Two cases of unusual cheiro-oral syndrome due to small pontine haemorrhage are described, in which both sides of the mouth were involved in the initial stage. High resolution magnetic resonance imaging revealed a small lesion at the paramedian pontine tegmentum in both cases and suggested involvement of the medial portion of the medial lemniscus.- - - - - - - - - - ranking = 3.1133853102965keywords = mouth (Clic here for more details about this article) |
8/10. Cheiro-oral-pedal syndrome in the lesion of thalamocortical projections.Unilateral sensory disturbance in the hand and mouth (cheiro-oral syndrome) is well known, but one in the hand, mouth and foot region (cheiro-oral-pedal syndrome) has been reported only in 2 patients with brainstem lesion and in 2 patients with thalamic infarction. We report the first case of cheiro-oral-pedal syndrome due to involvement of thalamocortical projections, which favors somatotopy in thalamocortical projections.- - - - - - - - - - ranking = 6.226770620593keywords = mouth (Clic here for more details about this article) |
9/10. Mental nerve anaesthesia as a result of mandibular metastases of prostatic adenocarcinoma.Three cases of mental nerve anaesthesia as a result of metastatic deposits from prostatic carcinoma are presented. They were referred to Consultant Oral and Maxillofacial Surgeons by alert GDPs. This highlights the fact that dental surgeons must be aware that systemic illness may manifest in the mouth and appropriate referral is essential.- - - - - - - - - - ranking = 3.1133853102965keywords = mouth (Clic here for more details about this article) |
10/10. Unilateral trismus caused by vertebrobasilar dolichoectasia.Vertebrobasilar dolichoectasia is a relatively uncommon pathological entity and generally asymptomatic. We report a quite unusual case of unilateral motor trigeminal involvement with trismus, due to VD. Apart from tetanus or local morbid conditions of the mouth, trismus is often attributed to disturbed programming and co-ordination of the masticatory muscles within the mesencephalic nucleus. The possibility of truncal compression of the trigeminal motor root by vertebrobasilar dolichoectasia being responsible for masseter muscle spasm, in analogy with the pathogenetic mechanisms proposed in hemifacial spasm, is proposed as an alternative explanation in the present case.- - - - - - - - - - ranking = 3.1133853102965keywords = mouth (Clic here for more details about this article) |
