A case of primary esophageal B-cell lymphoma of MALT type, presenting as a submucosal tumor.
The primary esophageal lymphoma is extremely rare, and shows various morphologic characteristics. Only a single case of mucosa-associated lymphoid tissue (MALT) type lymphoma confined to the esophagus has been reported in the literature. A 61-yr-old man was referred to our hospital for evaluation of an esophageal submucosal tumor (SMT) that had been detected incidentally by endoscopy. He had a history of pulmonary tuberculosis with long-term anti-tuberculosis medication 15 yr before, and also had a history of syphilis, which had been treated one year before. He had been taking a synthetic thyroid hormones for the past 10 months because of an autoimmune thyroiditis. Endoscopy showed a longitudinal round and tubular shaped smooth elevated lesion, which was covered with intact mucosa and located at the mid to distal esophagus, 31 cm to 39 cm from the incisor teeth. Endoscopic ultrasonography (EUS) showed a huge longitudinal growing intermediate- to hypo-echoic mass located in the submucosal layer with internal small, various sized honeycomb-like anechoic lesions suggesting germinal centers. Subsequently, he underwent a surgery, which confirmed the mass as a primary esophageal low-grade B-cell lymphoma of MALT type.

Use of detachable snares and elastic bands for endoscopic control of bleeding from large gastric varices.
BACKGROUND: Bleeding from gastric varices larger than 2 cm in diameter represents a major limitation for endoscopic hemostasis. METHODS: Endoscopic ligation of gastric varices was performed with detachable snares and elastic bands in 41 patients who had recent bleeding from gastric varices larger than 2 cm in diameter. Gastric varices larger than 2 cm were ligated with detachable snares, and then adjacent small gastric varices were ligated with elastic bands. RESULTS: Among the 41 patients, 10 of 12 patients with active bleeding and 28 of 29 patients with red color signs at initial endoscopy were successfully treated by endoscopic ligation by using detachable snares and elastic bands. Bleeding recurred early (before variceal eradication) in 4 of 38 patients (10.5%). The overall hemostatic rate for endoscopic ligation was 82.9% (34/41). In 33 of 36 patients (91.7%) who underwent repeated ligation treatments, variceal eradication was nearly complete. Mean follow-up in 30 of 33 patients after eradication of varices was 16.4 months (3-32 months), and 29 of 30 did not have recurrent bleeding. During and after ligation there were no serious complications. CONCLUSIONS: Endoscopic ligation therapy with large detachable snares and elastic bands is safe and effective for treatment of large bleeding gastric varices.

Wire-guided intraductal US in the assessment of bile duct strictures with Mirizzi syndrome-like features at ERCP.
BACKGROUND: Mirizzi syndrome refers to common hepatic duct obstruction caused by extrinsic compression that is usually from a stone impacted in the cystic duct. The utility of transpapillary intraductal US for assessment of biliary strictures with radiographic features of Mirizzi syndrome was studied retrospectively. METHODS: Intraductal US was performed in 16 patients with a common hepatic duct stricture caused by extrinsic compression and nonvisualization of the gallbladder by endoscopic retrograde cholangiography. An over-the-wire catheter US probe (20 MHz) was inserted into the bile duct. Intraductal US findings were compared with the final diagnoses at surgery. RESULTS: Intraductal US was successful in all patients. The extraluminal cause of the common hepatic duct stricture was detected in 14 patients (87.5%). In 9 patients, intraductal US detected an impacted stone outside the common hepatic duct. Intraductal US demonstrated extraluminal lesions without evidence of a stone in 5 patients, including a mass in 4 and asymmetrical, irregular thickening of the bile duct wall in 1 patient. In the remaining 2 patients, intraductal US demonstrated only a distended gallbladder. CONCLUSIONS: Transpapillary wire-guided intraductal US is useful for assessing biliary strictures with features that suggest Mirizzi syndrome and optimizes management of patients with these findings.

Biliary metal stent as a nidus for bile duct stone.
Several cases of recurrent stone formation caused by a surgical material as a nidus have been reported. Recently, we experienced one case in which a migrated metal stent might have been served as a nidus for common duct stone formation. The diagnosis was confirmed by ERCP, the stone was successfully removed with endoscopic therapy. Six years ago, she had undergone a lithotripsy using a percutaneous cholangioscopy (PTCS) because of intrahepatic bile duct stones. Six years later, she developed abdominal pain in the right upper quadrant. ERCP revealed the dilated extrahepatic bile duct and left intrahepatic bile duct and the presence of a large elongated freely mobile filling defect suggestive of common bile duct stone containing metal mesh in the distal common bile duct. The removed stone with endoscopic sphincterotomy was soft and dark brown in color with metal stent.

[A case of hepatocellular carcinoma with metastasis to gingival mucosa].
Hepatocellular carcinoma is one of the most common causes of death in Koreans. Most cases of hepatocellular carcinoma are beyond the stage of curative resection at the time of diagnosis due to extrahepatic metastasis as well as wide distribution of tumor in the liver. The lung is the most common site of extrahepatic metastasis but metastasis to gingiva is very rare in hepatocellular carcinoma. We report a case hepatocellular carcinoma with gingival metastasis in a 59 year old male patient.
