A Case of Epidermoid Cyst in the Intrapancreatic Accessory Spleen Mimicking Pancreas Mucinous Cystic Neoplasm / 대한췌담도학회지

An epidermoid cyst arising from intrapancreatic accessory spleen (ECIPAS) is a rare disease. Most patients with an ECIPAS are detected incidentally and could be misdiagnosed as a pancreatic cystic neoplasm such as mucinous cystic neoplasm (MCN) or intraductal p ancreatic mucinous neoplasm (IPMN). We described an ECIPAS with high cystic fluid carcinoembryonic antigen (CEA), which was misdiagnosed as a MCN of pancreas. Fifty one-year-old female was presented with a 2 cm sized non-enhancing pancreas cystic mass on the outside CT scan. Endoscpic ultrasonography (EUS) guided aspiration was performed. It showed a 2.3 x 1.9 cm unilocular cyst nearby 1.6 x 1.1 cm homogenous hypoechoic mass in pancreas tail, and cystic fluid CEA was 1564.18 ng/mL. On the basis of EUS results with elevated fluid CEA level, the presumptive diagnosis is likely to MCN of pancreas, and she underwent a laparoscopic distal pancreatectomy. The final pathology was the epidermal cyst in the intrapancreatic accessory spleen.

A Case of Gastric Ulcer Bleeding by Direct Connection to the Splenic Artery

Gastric ulcer bleeding is commonly encountered in emergency situations for gastroenterologist. Usually depth of gastric ulcer does not exceed the muscle layer. We report a case of a 67-year-old male with massive gastric ulcer bleeding caused by direct connection to the splenic artery. Bleeding control was not effectively performed by endoscopy due to massive bleeding with unstable vital sign. Angiography for embolization was performed. Active extravasation of contrast agents at the splenic artery stenosis was noted on splenic arteriogram. Bleeding stopped after embolization with histoacryl and lipiodol was successfully performed. After 1 month, complete ulcer healing was confirmed by follow up endoscopy. There was no evidence of invasive disease on biopsy.

Clinical Features of Non-alcoholic Fatty Liver Disease in Cryptogenic Hepatocellular Carcinoma / 대한소화기학회지

BACKGROUND/AIMS: Nonalcoholic fatty liver disease (NAFLD) may be one of the important causes of cryptogenic hepatocellular carcinoma (HCC). The aim of this study was to evaluate whether patients with cryptogenic HCC share clinical features similar to that of NAFLD. METHODS: Cryptogenic HCC was defined as HCC that occurs in patients with the following conditions: HBsAg(-), anti-HCV(-), and alcohol ingestion of less than 20 g/day. All patients diagnosed with cryptogenic HCC from 2005 to 2012 (cryptogenic HCC group), and all patients diagnosed with HBV associated HCC between 2008 and 2012 (HBV-HCC group) were enrolled in the present study. Clinical features, BMI, lipid profiles, presence of diabetes mellitus, hypertension, and metabolic syndrome were compared between the two groups. RESULTS: Cryptogenic HCC group was composed of 35 patients (19 males and 16 females) with a mean age of 70+/-11 years. HBV-HCC group was composed of 406 patients (318 males and 88 females) with a mean age of 56+/-7 years. Patients in the cryptogenic HCC group were older (p=0.001) and female dominant (p=0.042) than those in the HBV-HCC group. There were no differences in the laboratory test results including lipid profiles and Child-Turcotte-Pugh class between the two groups. Patients in the cryptogenic HCC group had higher prevalence of diabetes (37% vs. 17%, p=0.015), hypertension (49% vs. 27%, p=0.051), metabolic syndrome (37% vs. 16%, p=0.001), and higher BMI (25.3 kg/m2 vs. 24.1 kg/m2, p=0.042) than those in the HBV-HCC group. The tumor stage was more advanced (stage III and IV) at diagnosis in the cryptogenic HCC group than in the HBV-HCC group (60% vs. 37%, p=0.007). CONCLUSIONS: Cryptogenic HCC has clinical features similar to that of NAFLD and is diagnosed at a more advanced tumor stage.

Successful Treatment of Primary Biliary Cirrhosis with Adalimumab in a Patient with Overlap Syndrome

Primary biliary cirrhosis (PBC) is occasionally developed in patients with rheumatic diseases, such as systemic sclerosis or Sjogren's syndrome. However, there are a few reports of overlap syndrome with PBC. The authors report a case of a 36 year-old female with PBC and overlap syndrome. Systemic sclerosis was diagnosed in 2007, and rheumatoid arthritis in 2010. Adalimumab stopped because of her pregnancy plan in January 2012. One month after delivery, she felt increased hand joint pain and fatigue. Laboratory findings were as follows: elevated AST, ALT, ALP, r-GTP and positive anti-mitochondrial antibody. Histology of a liver biopsy revealed moderate porto-periportal and mild lobular inflammation with bile duct inflammation, which was consistent with PBC. She was treated with prednisolone and UDCA (urosodeoxycholic acid), but her disease was not controlled. From May 2013, she has been treated with adalimumab. Her arthritis was improved and liver function test normalized up until now.
