Although many cases of vascular malformations with phlebolithiasis have been reported, only few reports have documented cases of thrombosis formation. We report a rare case of a vascular malformation with multiple thromboses in the left buccal region. A 28-year-old woman had a painless swelling in the left cheek when she consulted our hospital. T1-weighted magnetic resonance imaging revealed a low-signal lesion, having the same intensity as the muscle, in the left buccal region, and T2-weighted imaging revealed a high-signal lesion. Additionally, three tuberous tumours were noted in this lesion showing both a light high signal on T1-weighted imaging and a low signal on T2-weighted imaging. Based on these imaging findings, as well as clinical and pathological findings, the patient was diagnosed with multiple vascular malformations in the left midfacial region. The three tuberous tumours showed necrotic tissue in the central area, which was formed by calcified and concentric fibrous tissue, and vascularization. Because tumorous lesion and typical vascular structure by the Elastica Van Gieson staining were not observed, these tumours were seemed that fibrin thrombus in this lesion formed the organized tissue.展开更多

2008年对于EVG公司来说是又一个增长年，业绩成长了15．20％，尤其扩大了在纳米压印光刻、3D／TSV封装领域的市场占有率。尽管2009年整体宏观经济和环境预计将更复杂和具有挑战性，特别影响在汽车制造与消费类产品市场中，但我们期待有更多新颖的技术，例如后部照明的（英国标准协会）图像传感器或者采用更高功能密度的移动电话，这都将带动EVG在三维集成电路封装设备（例如，光刻以及永久和临时晶圆键合）的市场占有率将会继续成长。展开更多
