ABSTRACT
Small cell neuroendocrine carcinoma in the ampulla of Vater is a rare disease and there have only been three cases reported in Korea. In these three cases, the patients had symptoms of abdominal pain and jaundice. A biopsy via endoscopic retrograde cholangiopancreatography confirmed a small cell neuroendocrine carcinoma; thus, each patient underwent surgical treatment. Recently, we experienced a case of small cell neuroendocrine carcinoma in an asymptomatic patient. An ulcerative lesion was identified during screening gastroduodenoscopy. Here, we report this case and review the relevant literature.

Nephrotic syndrome results in a prolonged, heavy increase in glomerular permeability to proteins. Nephrotic syndrome caused by malignant neoplasms accounts for 7.9% to 10.9%. Nephrotic syndrome can improve following resection of gastric malignancies. However, the relationship between early gastric cancer and nephrotic syndrome has not been elucidated. We report a case of early gastric cancer with nephrotic syndrome that improved after resection of the primary gastric lesion by endoscopic submucosal dissection.

BACKGROUND/AIMS: The purpose of this study is to verify the risk factors associated with Dieulafoy lesion formation in the upper gastrointestinal tract. METHODS: A case-control study was performed by reviewing the electronic medical records of 42 patients who were admitted to a tertiary medical center in the Daejeon region for Dieulafoy lesions from September 2008 to October 2013, and the records of 132 patients who were admitted during the same period and who underwent endoscopic examination for reasons other than bleeding. We analyzed clinical and endoscopic findings retrospectively, and searched for risk factors associated with Dieulafoy lesion formation. RESULTS: All 42 patients diagnosed with Dieulafoy lesion had accompanying bleeding, and the location of the bleeding was proximal in 25 patients (59.5%), the middle portion in seven patients (16.7%), and distal in 10 patients (23.8%). Antiplatelet agents (p=0.022) and alcohol (p=0.001) use showed statistically significant differences between the two groups. The odds ratios (95% confidence intervals) of the two factors were 2.802 (1.263 to 6.217) and 3.938 (1.629 to 9.521), respectively. CONCLUSIONS: This study showed that antiplatelet agents and alcohol consumption were risk factors associated with Dieulafoy lesion formation in the upper gastrointestinal tract.

Carcinosarcoma of the stomach is a rare biphasic tumor that consists of both carcinomatous and sarcomatous components. In the gastrointestinal tract, carcinosarcoma is most frequently seen in the esophagus and rarely in the stomach. Tubular or papillary adenocarcinomas are common carcinomatous components, whereas mesenchymal sarcomatous components may vary. Neuroendocrine carcinomatous differentiation in carcinomatous components is extremely rare. We report a 62-year-old female patient with a history of dyspepsia for one-month-history. Endoscopic findings showed a ulcerofungating lesion, which infiltrated from the posterior wall of the antrum to the posterior wall of the gastric angle. Radical subtotal gastrectomy was performed. In the resected specimen, immunohistochemical studies showed two positive reactions for epithelial and mesenchymal markers. Based on the above findings, the patient was diagnosed with a gastric carcinosarcoma with neuroendocrine differentiation.
