Inflammatory Pseudotumor of the Liver Mimicking an Infiltrative Malignancy / 계명의대학술지

Inflammatory pseudotumor (IPT) is a relatively rare and benign disease characterized by chronic inflammatory cell infiltration with fibrosis. It is difficult to diagnose IPT because of the absence of specific symptoms or unique radiological findings. IPT can be mistaken for a malignant tumor, such as cholangiocarcinoma or hepatocellular carcinoma, due to their similar clinical and radiological findings. Unfortunately, hepatic resection is often performed due to misdiagnosis. Presented here is a case of a woman aged over 60 years who presented with general weakness lasting more than one month and unexplained body weight loss.

Predictable Factors of Histologic Discrepancy of Gastric Cancer between the Endoscopic Forceps Biopsy and Endoscopic Treatment Specimen / 대한소화기학회지

BACKGROUND/AIMS: Recently, variable gastrointestinal track tumors including early stage malignancies are treated by endoscopic procedure. However, the discrepancy of histologic diagnosis may sometimes exist between the pretreatment forceps biopsy results and those of post treatment specimen. So the prediction of malignant lesion is important in the aspect of treatment selection. In this study, we investigated the predictable factors of the histologic discrepancy through the clinical, endoscopic features of the lesion diagnosed as adenocarcinoma in the post-endoscopic treatment specimen after the adenoma was diagnosed by the endoscopic forceps biopsy. METHODS: From March 2005 to April 2009, 129 gastric tumor lesions (129 patients) which were not diagnosed as malignancy and treated with endoscopic procedure were enrolled retrospectively. We compared the pretreatment endoscopic forceps biopsy results and post-treatment specimen biopsy results, then, analyzed the tumor characteristics. RESULTS: Twenty-one cases (16.3%) were diagnosed as malignancy after endoscopic treatment. Especially, discrepancy occurred more frequently in depressed lesions than in flat or elevated lesions (41.7% vs. 13.7%, p=0.012), and in lesions diagnosed as high grade adenomas than low or moderate grade adenomas (33.3% vs. 11.1%. p=0.004). CONCLUSIONS: In cases of depressed type lesions in the pretreatment endoscopy or those diagnosed as high grade adenoma in the pretreatment forceps biopsy, we should consider combined malignant lesion. Therefore, treatment modalities ensuring accurate diagnosis and potentially curative resection, should be carefully selected and performed in cases which have these features.

Pancreatic and Biliary Strictures Associated with Cholangitis and Bile Reflux Following Endoscopic Papillectomy of Ampullary Adenoma / 대한소화기내시경학회지

Ampullary adenoma is rare but clinically important because it is a premalignant lesion. Use of endoscopic gastroduodenoscopy has increased detection of adenoma of the major duodenal papilla. Endoscopic papillectomy is a promising technique to supplant surgical ampullectomy, because it is less aggressive and more stable. However, various complications include bleeding, perforation, pancreatitis and cholangitis. We describe pancreatic and biliary strictures associated with cholangitis, and bile reflux through the pancreatic duct to the minor duodenal papilla after endoscopic papillectomy. Pancreatic and biliary strictures have not been hitherto reported complications. We performed endoscopic papillary balloon dilatation, minor papilla papillotomy and inserted a drain tube through the accessory pancreatic duct.

Non-Ischemic Cardiomyopathy Attributed to Adult Myotonic Dystrophy

In patients with myotonic dystrophy (MD), impairment of the conduction system is a common and progressive finding. However, only a few cases of MD with cardiomyopathy have been reported. Herein we report a case of MD with progressive non-ischemic cardiomyopathy and severe electrocardiographic abnormalities.

Carotid Sinus Syncope in an Elderly Patient With Unexplained Syncope

Carotid sinus syndrome is the most commonly reported cause of falls and syncope in elderly adults. However, it has been rarely reported in Koreans, and the reason of this ethnic difference is unknown. We report here on an Korean unusual case of carotid sinus syncope and this was induced by carotid sinus massage.
