Ewing's sarcoma (ES) is a neoplasm of undifferentiated small round cells, which occurs in the bones and deep soft tissues of children and adolescents. We present a rare case of a 44-year-old woman with gastric ES presenting with epigastric pain and weight loss. Ultrasound and computed tomography scans indicated a solid/cystic mass in the pancreatic tail. At laparotomy, the tumor was found attached to the posterior surface of the stomach, completely free from the pancreas, with no lymphadenopathy or local metastases. The polynodal, partly pseudocystic, dark-red soft tumor was excised. Histopathology revealed an anaplastic small-round-cell tumor with strong membranous CD99 immunoexpression. Additionally, there was patchy immunostaining for S-100 protein, vimentin, protein gene product (PGP) 9.5 and neuron-specifi c enolase, and weak focal CD117 cytoplasmic immunoreactivity. The patient had no adjuvant chemotherapy; her postoperative recovery was uneventful, and she remains symptom-free, and without any sign of recurrence at 20 mo. To the best of our knowledge, this is only the third ever case of gastric ES.

AIM： To estimate the characteristics of Color Doppler findings and the results of hepatic radionuclide angiography （HRA） in secondary Hodgkin＇s hepatic lymphoma. METHODS： The research included patients with a diagnosis of Hodgkin＇s lymphoma with metastatic focal lesions in the liver and controls. Morphologic characteristics of focal liver lesions and hemodynamic parameters were examined by pulsed and Color Doppler in the portal, hepatic and splenic veins were examined. Hepatic perfusion index （HPI） estimated by HRA was calculated. was observed. Lesions were mostly hypoechoic and mixed, solitary or multiple. Some of the patients presented with dilated splenic veins and hepatofugal blood flow. A pulse wave was registered in the centre and at the margins of lymphoma. The average velocity of the pulse wave was higher at the margins （P 〉 0.05）. A continuous venous wave was found only at the margins of lymphoma. There was no linear correlation between lymphoma size and velocity of pulse and continuous wave （r = 390, P 〈 0.01）. HPI was significantly lower in patients with lymphomas than in controls （P 〈 0.05）, pointing out increased arterial perfusion in comparison to portal perfusion. CONCLUSION： Color Doppler ultrasonography is a sensitive method for the detection of neovascularization in Hodgkin＇s hepatic lymphoma and estimation of its intensity. Hepatic radionuclide angiography can additionally help in the assesment of vascularisation of liver lesions.

采用传统电子陶瓷的制备工艺,制备了相同Bi_2O_3含量、Sb_2O_3/Bi_2O_3比分别为0.25、0.50的ZnO-Bi_2O_3基压敏陶瓷,研究在800℃-950℃区间内一步烧结与两步烧结制度对陶瓷的显微结构与电性能的影响。显微结构分析表明,烧结过程中足够的Bi_2O_3液相有利于烧结,而且能够促进晶粒内含反演边界(Inversion Boundary)的ZnO晶粒的长大。烧成的样品具有发育良好的显微结构:高的致密度、均匀的含Bi第二相分布以及粒径,而且电性能良好:压敏电压327-670 v/mm,非线性系数20-31,漏电流低于0.5μA。Sb_2O_3含量较高的样品,晶粒尺寸较小,压敏电压和非线性系数较大,漏电流较小。研究还发现,ZnO晶粒尺寸以受两步烧结制度里占主要的烧结过程的影响为主。研究结果表明:与传统的1000℃以上烧结相比,合理的配方是保证在800℃-950℃区间内烧结获得综合性能良好的压敏陶瓷样品的关键。
