Lymphoepithelial cyst of the pancreas is a rare benign cystic tumor which is histologically characterized by cyst containing keratin, lined by mature squamous epithelium surrounded by lymphoid tissue, often with prominent follicles. Cystic lesions of the pancreas are more often detected because sensitive abdominal imaging tests are used for multiple indications, but preoperative differential diagnosis is difficult despite the advancements of imaging technologies. We herein report a case of lymphoepithelial cyst incidentally found on routine abdominal ultrasonography which showed characteristic findings on endoscopic ultrasonography preoperatively and discuss the radiologic features of lymphoepithelial cyst. 췌장의 림프상피성 낭종은 조직검사에서 케라틴화된 상피세포와 림프구의 침윤을 특징으로 하는 췌장의 드문 양성 낭성종양이다. 최근 영상진단의 발전과 함께 췌장의 무증상의 낭성종양의 발견율이 증가하고 있지만 여전히 췌장의 낭성종양의 수술 전 감별 진단은 어렵다. 저자들은 최근 건강검진에서 우연히 발견된 췌장의 낭성종괴에 대한 수술 절제술 후 진단된 췌장의 림프상피성 낭종을 경험하였기에 이를 문헌 고찰과 함께 방사선학적 감별 진단 및 내시경초음파의 유용성을 중심으로 보고하는 바이다.

췌장암은 악성종양의 5% 이하를 차지하며, 피부전이는 매우 드물다. 저자들은 결정성 전신피부병변으로 내원한 환자에서 초음파와 컴퓨터단층 촬영상 췌장종괴가 발견되고 CA 19-9이 매우 높았으며 피부조직 검사를 시행한 결과 전이성 선암으로 판정되어 췌장암에서 유래된 피부전이암으로 진단되어진 증례를 접하고 문헌고찰과 함께 보고한다. Carcinoma of the pancreas represents less than 5% human malignant neoplasm. It's skin involvement is rare. A 73 year-old man presented with multiple skin lesions located on the face, neck and body. The histopathologic study of the skin lesion was confirmed to be an metastatic adeno-carcinoma. The primary tumor was regarded as the mass at the head of the pancreas observed on the CT scan, but was not confirmed by biopsy. We report a case of multiple cutaneous metastasis from pancreatic carcinoma with brief review of related literature.

복강경 담낭 절제술은 담낭 결석 및 용종 등의 담낭 질환의 치료법으로 널리 이용되고 있다. 드물게 이 수술의 합병증으로 클립의 총담관, 십이지장 및 폐동맥으로 이동이 보고되고 있다. 복강경 담낭 절제술 후 복통, 황달, 발열, 오심, 구토 등의 담관염 증세가 있으며, 추적 단순 방사선 소견에서 우상복부에 존재하는 클립의 위치 변화가 있을때, 클립의 이동에 의한 총담관 폐색을 의심해 보아야 한다. 저자들은 내원 7개월 전 복강경 담낭 절제술을 시행받았던 환자에서 외과적 클립의 이동으로 초래된 총담관 부분 폐색을 내시경적 역행성 담관조영술로 진단하고 제거하였기에 이를 문헌고찰과 함께 보고하는 바이다. The laparoscopic cholecystectomy, which was originally developed in Europe, is now gaining wide acceptance due to a less painful surgery, a shortened hospital stay and less scarring. But the laparoscopic cholecystectomy were reported serious complications such as, gallbladder bed hemorrhage, bile duct injury, jejunal perforation and rarely dislocation and migration of the surgical clips. We report a 61-year-old man with obstructive jaundice that was generated surgical clips migration into the common bile duct, who had undergone a laparoscopic cholecystectomy because of acute calculous cholecystitis 7 months ago. Abdominal CT scan revealed multiple clips into the distal CBD and mild dilatation of intrahepatic biliary tree. The clips were removed using basket after endoscopic sphincterotomy.

Background: We have doubt about the truth that Type 2 DM is associated with chronic hepatitis C infection. The aim of our study was to prove a close relationship between chronic HCV infection and type 2 DM in korean patients. Methods: We reviewed the out-patient's medical records of 466 patients with type 2 DM who visit the Sung-ae hospital from March 2000 to August 2001. Diabetic patients were analyzed for the following variables: age, sex, waist circumference, weight, waist/hip ratio, using of self monitoring of blood glucose, method of therapy, duration of disease, experience of previous transfusion, major surgical procedure, accompanied disease, liver function tests (LFT), HbA1 c. We ruled out patients with liver cirrhosis. Results: Hepatitis C virus infection was observed more frequently in patient with Type 2 DM. Of 466 Type 2 DM patients, 13 patients were infected with Hepatitis C virus (2.79%). Compared with mean prevalence of Korean population (1.3~1.6%), it's value is very high. the other hand, 21 patients were infected with Hepatitis B virus (4.5%). Such results are similar to mean prevalence of the general public (4~5%). Conclusions: Prevalence of hepatitis C was closely associated in korean patients with type 2 DM. And an increased prevalence is independent of cirrhosis.
