We found a pediculate, hard, elastic mass measuring 38 mm （cross-sectional diameter）. Computed tomography （CT） scans and dynamic magnetic resonance imaging （MRI） confirmed irregularly shaped mass and revealed a heterogeneous internal composition, consistent with vascular tumors. We excised the tumor under general anesthesia. Histopathological diagnosis was based on positive immunoreactivity of CD99 and vimentin and weak, positive staining of CD34. Three and half years following tumor excision, there is no recurrence or metastasis.展开更多

Materials and Methods: The study group comprised 250 patients with dry mouth and 241 healthy volunteer subjects at 13 medical centers. This device was used to measure the moisture degrees of the lingual mucosa and the buccal mucosa. Subjective oral dryness, objective oral dryness, and saliva flow rates were also compared between the two groups. For statistical analysis, receiver-operating characteristic analysis was performed to calculate the area under the curve (AUC). Results: The moisture degree of the lingual mucosa was significantly lower in the dry mouth group (27.2 ± 4.9) than that in the healthy group (29.5 ± 3.1, AUC = 0.653). When a lingual mucosa moisture degree of 31.0 or higher was defined as normal, less than 27.0 as dry mouth, and 27.0 to less than 31.0 as borderline zone of dry mouth, both the sensitivity and the specificity for the diagnosis of dry mouth were close to 80%. Conclusion: These results suggest that the oral moisture-checking device is a usable screening device for dry mouth.展开更多

After neoadjuvant chemoradiotherapy, the patient underwent segmental resection of the right mandible and right radical neck dissection. Surgical specimens confirmed remarkable nodal metastases. Unfortunately, the patient experienced a rapid fatal outcome, and numerous distant metastases were detected on autopsy. Moreover, postoperative 18F-fluorodeoxyglucose- positron emission tomography/computed tomography detected systemic distant metastases in this case. In our opinion, the use of preoperative FDG-PET/CT should be considered for patients with suspected poor prognoses.展开更多
