A case of hemangiopericytoma of the soft palate with articulate disorder and dysphagia

International Journal of Oral Science 2013年第2期5卷 111-114页

We report a case of hemangiopericytoma of the soft palate of 60-year-old patient, who noticed a mass of the soft palate and experienced difficulty in speaking. 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.

ICE 是新一代的面向对象中间件平台,开发者只需付出很少的努力,就能够用 ICE构建出分布式客户——服务器应用。ICE 在概念上与 CORBA 类似,但在许多方面都有突破性的进展:它的对象模型更简单、更强大;解决了过去困扰中间件的低效问题;提供了许多新特性,比如支持用户数据报协议(UDP)、异步方法分派、内建的安全性、自动的对象持久,以及接口聚合。本文将讨论 ICE 的各种设计决策、对比 CORBA 和 ICE 所采用的不同方法,并概述 ICE 的设计所带来的好处。

We experienced a case of oral squamous cell carcinoma of the mandible with scattered distant metastases. 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.
