        Solid pseudo-papillary neoplasm (SPN) of pancreas is a rare epithelial neoplasm of pancreas with a low malignant potential, occurs most commonly in young females. Here, we report a rare case of woman who has severe hepatomegaly due to multiple hepatic metastases of SPN of pancreas. At the time of diagnosis, a SPN was detected at only pancreas and there was no evidence of metastasis. So, she received subtotal pancreatectomy and total splenectomy. After 2 years of follow up, multiple small hepatic metastases were presented. In spite of three times of radiofrequency ablation, the burden of hepatic metastasis has increased continuously and multiple intra-abdominal lymph nodes metastases were detected, and ascites and peripheral edema occurred. However, because of benign feature of SPN and extremely rare incidence of recurrence and metastasis, there is no specific treatment guideline for metastatic SPN. Through multidisciplinary care service, we planned to do radiotherapy followed by a transarterial chemoembolization (TACE). But the patient could not have a scheduled radiation therapy due to deterioration of liver function. So changing the strategy of treatment, followed by TACEs were done alone. Although the size of SPN is not reduced, the extent of SPN and complication of SPN (ascites, peripheral edema, abdominal pain and so on) are being controlled. (J Liver Cancer 2018;18:168-174)

      • 3D 애니메이션을 이용한 게임 트레일러 제작 연구

        허예림(Heo Ye-Rim),김미리(Kim Mi-Ri),김유경(Kim You-Gyung),서동희(SeoDong-Hee),김태은(KimTae-Eun) 한국정보기술학회 2017 Proceedings of KIIT Conference Vol.2017 No.12

        본 논문은 ‘찰리의 솜사탕’ 립모션 게임의 3D 애니메이션 트레일러 제작에 관한 연구이다. 솜사탕을 쫓아가며 자동차를 위험으로부터 지켜야 하는 게임에 앞 내용을 보여주는 애니메이션을 재미있는 내용으로 제작하였다. 본 연구에서는 어떻게 더 영상을 예쁘게, 볼거리가 많게 보여줄 수 있는 지에 대한 제작 과정에 대해 기술하였다.

        동시성으로 발생한 폐 편평세포암종과 흉곽내 광범위큰B세포림프종 1예

        동시성 다발성 중복암의 경우 각각의 암종별 병기 설정과 치료 계획을 결정하기 어려운 경우가 많다. 특히 폐암과 비호지킨림프종 모두 종격동과 폐문 림프절을 침범할 수 있기때문에, 이 두 암종이 동시에 공존하는 경우는 폐암의 병기를 결정 짓기 어렵다. 본 증례는 국내에서 동시성으로 발생한 편평상피세포 폐암과 종격동 림프종을 진단한 첫 번째 보고로써, 조직학적 확인의 중요성과 동시 다발성 중복암의 가능성을 간과해서는 안됨을 제시하고 있다. 이에 저자들은 우측 흉수를 주소로 내원한 65세 남자에서 기관지경 생검 및 초음파 유도하 경기관지 세침흡인술을 통해 폐의 편평세포암종과 흉곽의 광범위큰B세포림프종이 동시성으로 발생한 중복암을 진단한 1예를 문헌고찰과 함께 보고하는 바이다. A 65-year-old male was referred to our hospital for evaluation of a right pleural effusion. Thoracic computed tomography (CT) revealed a huge central mass with right hilar and subcarinal lymph node conglomerates. An endobronchial mass was incidentally found in the right upper lobe bronchus, and endobronchial ultrasound-guided transbronchial needle biopsy of the mediastinal lymph nodes was thus also performed at the time of bronchoscopy. The two biopsies revealed squamous cell carcinoma and diffuse large B-cell lymphoma (DLBCL), respectively. As the pathology of the mediastinal lymph nodes was unknown, the lung cancer could not be accurately staged. Thus, we treated the DLBCL; follow-up positron emission tomography/CT after two cycles of chemotherapy showed that the conglomerate mass had disappeared but the right upper lobe lesion remained. Lung cancer staging thus became more accurate and radical treatment could be considered. To the best of our knowledge, this is the first report of a co-existing squamous cell carcinoma of the lung and DLBCL of the intrapulmonary lymph nodes. (Korean J Med 2018;93:300-305)

        Helicobacter pylori의 Kato III 세포내 발견

        백승철,이정희,고경혁,조명제,조중현,김유경,윤희상,이우곤,이광호,강수민 대한소화기학회 1998 대한소화기학회지 Vol.31 No.6

        Background/Aims; Some investigaters reported that the invasion of H. pylori into the gastric epithelial cells or lamina propria had been detected by light microscopie examination using various staining methods (i,e. the Warthin-Starry stain, immunohistologic stain) or by electron microscopic examination. However, the results are hardly convinced because they may be nonspecifically stained, or the intracytoplasmic organelles of the gastric epithelial cells may be mistaken for bacteria. Thus, we combined an immunohistologic method with an electron microscopy to deterrnine whether H. pylori is invasive into the gastric epithelial cells. Metbods: To enhance bacterial invasion, we adapted an in vitro system using Kato III cells, a gastric carcinoma eell line. The cells were infected with H. pylori. The infection was confirmed by staining with polyelonal antibody against H. pylori. and an electron microscopy. Resnlts: H. pylori was found within the cytoplasm of several Kato III cells. The intracellular bacteria could be differentiated from intracellular organelles or other bacteria-looking materials by gold particles attached to the bacteria, Conclusions: We could not elucidate the invasiveness of H. pylori, but we found the presence of H. pylori in the cytoplasm of the Kato III cells. These results indicate that the invasiveness of H. pylori will remain as one of the factors participating in the pathogenesis oF H. pylori-induced chronic gastritis and peptic ulcer. Further studies will be needed to demonstrate the invasiveness of H. pylori.
