促结缔织增生的小圆房间肿瘤(DSRCT ) 是有特殊组织学的特征的稀罕、高度好攻击的恶意：在稠密的促结缔织增生基质以内的细胞的生长的一个嵌套的模式，与男优势发生在年轻人口。吝啬的幸存时期仅仅关于 1.5-2.5 年。肿瘤共同表示上皮，在免疫的肌肉，和神经标记组织化学的研究。这个工作报导与吐血和长期的便秘介绍的一个 27 岁的人。包括内视镜检查法，上面的胃肠的系列，腹的计算断层摄影术和钡灌肠的连续研究学习内脏的机关的显示出的传播参与。病人经历了好攻击的外科并且收到了由 5 氟尿嘧啶，出租机动三轮车磷酰胺， etoposide， doxorubicin，和 cisplatin 组成的手术后的辅助化疗。没有任何疾病，他在外科以后为 20 瞬间幸存。没有标准疗法协议被建立了。与手术后的多代理人助手化疗相结合的好攻击的外科被认为正当不仅减轻症状而且试着在这个先进 DSRCT 年轻病人改进结果。

Clinicopathological study of solid and pseudopapillary tumor of pancreas: Emphasis on magnetic resonance imaging findings

AIM: To report the clinicopathological features and magnetic resonance imaging (MRI) findings of solid and pseudopapillary tumor (SPT) of pancreas.METHODS: From 1981 to 2005, 26 surgically treated cases of SPT were retrospectively reviewed. MRI findings of the latest 11 consecutive SPT cases were investigated.RESULTS: There were 25 women and one man having SPT (median age: 23 year) with a median tumor size of 7.5 cm. Among them, nine patients developed solid pseudopapillary carcinoma. During the median follow-up period of 66 mo, the 5-year survival rate of the 26 SPT patients was 96.2%. Three MRI features were proposed including Type 1 image, displaying SPT with completely solid part. All SPT patients with type 1 image were detected incidentally. Type 2 image displays of SPT with solid mass hemorrhage and type 3 image with massive hemorrhage. All the eight SPT patients with type 2 and 3 images suffered abdominal pain due to hemorrhage from SPT.CONCLUSION: SPT had a favorable survival rate irrespective of surgical procedures, malignancy, and MRI findings, however, MRI could reliably correlate with its clinicopathological features.

Liver metastasis from hepatoid adenocarcinoma of the stomach mimicking hepatocellular carcinoma: Dynamic computed tomography findings

AIM: To evaluate the dynamic computed tomography(CT) findings of liver metastasis from hepatoid adenocarcinoma of the stomach(HAS) and compared them with hepatocellular carcinoma(HCC).METHODS: Between January 2000 and January 2015, 8 patients with pathologically proven HAS and liver metastases were enrolled. Basic tumor status was evaluated for the primary tumor location and metastatic sites. The CT findings of the liver metastases were analyzed for tumor number and size, presence of tumor necrosis, hemorrhage, venous tumor thrombosis, and dynamic enhancing pattern.RESULTS: The body and antrum were the most common site for primary HAS(n = 7), and observed metastatic sites included the liver(n = 8), lymph nodes(n = 7), peritoneum(n = 4), and lung(n = 2). Most of the liver metastases exhibited tumor necrosis regardless of tumor size. By contrast, tumor hemorrhage was observed only in liver lesions larger than 5 cm(n = 4). Three patterns of venous tumor thrombosis were identified: direct venous invasion by the primary HAS(n = 1), direct venous invasion by the liver metastases(n = 7), and isolated portal vein tumor thrombosis(n = 2). Dynamic CT revealed arterial hyperattenuation and late phase washout in all the liver metastases.CONCLUSION: On dynamic CT, liver metastasis from HAS shared many imaging similarities with HCC. For liver nodules, the presence of isolated portal vein tumor thrombosis and a tendency for tumor necrosis are imaging clues that suggest the diagnosis of HAS.

Correct diagnosis and successful treatment for pericardial effusion due to toothpick injury: A case report and literature review

We reported a 55-year-old man who suffered from chest pain and dyspnea on exertion for two weeks associated with night sweating, general malaise, poor appetite, and body weight loss. Physical examination revealed friction rub with distant heart sound, bilateral clear breathing sound, no abdomen tenderness, and normal bowel sound. Subsequent chest X-ray revealed cardiomegaly and cardiac echo showed massive pericardial and pleural effusion with normal left ventricular function. Constrictive pericarditis was diagnosed based on clinical information. Tuberculosis (TB), malignancy, autoimmune disease, infection, hypothyroidism, and idiopathic could be the causes but excluded by further study. High-resolution lung CT scan after reconstruction revealed a moderate amount pericardial effusion with possible superimposed infection. Thickness of pericardium and left lobe liver abscess were found. A straight tubular structure about 6 cm in length transverses the lateral segment of liver to pericardial space and unknown foreign body was suspected. Laparotomy was performed, 6.5 cm toothpick was found through the liver into pericardium. Post-operative course was uneventful and he discharged one week later. The patient could not remember swallowing the toothpick before. He had no chest pain and dyspnea on exertion during a 6-mo follow-up period.

Isolated varices over hepatic flexure colon indicating superior mesenteric venous thrombosis caused by uncinate pancreatic head cancer - a case report

Very rare cases of varices involving right side colon were reported. Most of them were due to cirrhotic portal hypertension or other primary causes. No report case contributed to pancreatic cancer. Here, we reported a case of uncinate pancreatic cancer with the initial finding of isolated hepatic flexure colon varices. Following studies confirmed isolated varices involving hepatic flexure colon due to pancreatic cancer with occlusion of superior mesenteric vein. From this report, superior mesenteric vein occlusion caused by uncinate pancreatic head cancer should be considered as a differential diagnosis of colon varices.
