( Ah Lon Jung ),( Semi Kim ),( Sung Soo Kim ),( Dong Goo Kang ),( Seung Uk Lee ),( Sang Ki Cho ) 대한내과학회 2015 대한내과학회 추계학술대회 Vol.2015 No.1
A 76-year-old man with no known coronary artery disease presented to an outside hospital with cough, shortness of breath and low extremity edema. An initial resting electrocardiogram revealed Q-wave and ST segment elevation in leads V4-6 and Q-wave in leads II, III, and aVF. Chest X ray showed pulmonary congestion in both lung fields with cardiomegaly. Lab testing revealed troponin I of 0.36 ng/mL, troponin T of 0.165 ng/mL and pro-BNP of 2,749 pg/mL. Transthoracic echocardiography revealed apical akinesia with depressed left ventricular (LV) function, and an estimated ejection fraction of 39%. Emergent coronary angiography showed the posterolateral branch of the right coronary artery (RCA) communication with the distal left circumflex artery (LCx) without significant obstructive lesion in the left coronary arteries (LCA) and the RCA. Simultaneous bilateral coronary angiography showed bi-directional blood flow between distal RCA and LCx. The patient was maintained on a angiotensin receptor blocker, diuretics and aspirin by the suspicious stress induced cardiomyopathy. Follow up echocardiography revealed improved LV systolic function with apical wall motion after 1 month, and has remained symptom-free since.

Most cases of gastric subepithelial lesions follow a good clinical course; however, some lesions progress to malignant tumors,and treatment of tumors with a high risk of malignancy is essential. Surgical excision has been the primary treatment for tumorsoriginating from the propria muscle layer, but it has the disadvantages of being invasive and causing postoperative functionalabnormalities. With the development of endoscopic techniques and instruments, the role of endoscopic resection, which is a lessinvasive method for the removal of gastric subepithelial lesions, has been attracting attention. We performed an endoscopic fullthicknessresection for 8 patients with gastric subepithelial lesions originating from the muscularis propria. No fatal complicationsoccurred. Our findings suggest the need to develop various devices for resection and closure and to accumulate further experiencethrough additional studies to prevent complications and specimen loss.

Carcinoma of the gallbladder is the most common biliary tract tumor. Signet ring cell carcinoma of the gallbladder is a rare form of mucinous adenocarcinoma and has a worse prognosis. Since very few cases have been reported, information regarding the behavior and prognosis of gallbladder signet ring cell carcinoma is limited. Only eight cases of signet ring cell carcinoma of the gallbladder have been reported so far. Four cases of these had lymph node metastasis and died within 3 months. The other cases had no information of outcome. We present a rare case of primary signet ring cell carcinoma of the gallbladder. A 58-year-old male presented to our hospital with complaints of epigastric pain. Abdominal computed tomography showed multiple gallbladder stones with diffuse wall thickening, cystic duct enhacement and CBD stone. Removing CBD stone through ERCP, laparoscopic cholecystectomy was performed. The histopathologic finding revealed that diffusely growing adenocarcinoma of signet ring cell type was noted in the surface epithelium with intracellular mucin (Fig. 1). The immunohistochemical stain for cytokeratin was positive for tumor cells (Fig. 2). The final pathologic result was signet ring cell carcinoma of the gallbladder. There was no metastasis in the retroperitoneum and mesenteric lymph node. The tumor was stage IIIA (according to TNM staging). As Esophagogastroduodenoscopic finding showed no evidence of malignancy. He is planning to perform extended radical cholecystectomy and post-operative chemotherapy.

Background and Objectives: Radiofrequency ablation has recently been used for the treatment of benign thyroid nodules, with outstanding results. However, in most studies, the procedure was usually performed by a radiologist or surgeon. This study aimed to evaluate the efficacy and safety of radiofrequency ablation for nodules >2 cm performed by an endocrinologist with several years of experience performing fine-needle aspiration cytology. Materials and Methods: This study was a cross-sectional analysis of 111 patients who received radiofrequency ablation between April 2010 and July 2013. A total of 73 patients with 75 nodules >2 cm in diameter with at least 6 months of follow-up examinations were included. Results: The mean follow-up period was 11.5 months. The mean nodule volume decreased from 17.0±15.3 mL preoperatively to 6.0±8.5 mL postoperatively, with a mean volume reduction of 69.7%. There were no major complications, and only 1 patient (1.3%) presented with a minor complication (hemorrhaging of the thyroid parenchyma). Conclusion: Radiofrequency ablation is a safe method for reducing benign thyroid nodules, and is not associated with any major complications.
Single Nodular Pulmonary Amyloidosis: Case Report

Amyloidosis is defined as the presence of extra-cellular deposits of an insoluble fibrillar protein, amyloid. The pulmonary involvement of amyloidosis is usually classified as tracheobronchial, parenchymal nodular, or diffuse alveolar septal. A single nodular lesion can mimic various conditions, including malignancy, pulmonary tuberculosis, and fungal infection. To date, only one case of nodular pulmonary amyloidosis has been reported in Korea, a case involving multiple nodular lesions. Here, we report and discuss the case of a patient having single nodular amyloidosis.
