RESUMO
Gastric adenocarcinoma of fundic gland type is known to originate from the gastric mucosa of the fundic gland region without intestinal metaplasia. It is difficult to detect during endoscopy and diagnose histopathologically. The development of immunohistochemistry has enabled the diagnosis of gastric adenocarcinoma of fundic gland type by gastric phenotype. A 34-year-old man visited us for treatment of a 5 cm-sized low-grade dysplasia in the gastric fundus which was incidentally found during a health check-up endoscopy. Endoscopic submucosal dissection was performed successfully, and the final histopathology showed gastric adenocarcinoma of fundic gland type. Herein, we report a rare case of gastric adenocarcinoma of fundic gland type and its endoscopic and histopathologic findings.

RESUMO
Glomus tumor is a benign tumor derived from the vascular wall of the arteriovenous anastomosis complex. Glomus tumors in the gastrointestinal tract are rare, especially those in the duodenum. Most gastrointestinal glomus tumors are found incidentally on endoscopy during routine health checkup and sometimes because of bleeding. We experienced a case of duodenal glomus tumor diagnosed after surgical resection of an incidental subepithelial tumor in the duodenum. Herein, we report the characteristic endoscopic ultrasonography, contrast-enhanced CT, and histopathological findings of duodenal glomus tumor.

RESUMO
PURPOSE: We evaluated the clinicopathological charicterics and prognostic impacts of lymphatic vessel invasion in gastric cancer without lymph node involvement. MATERIALS AND METHODS: Among 1,795 patients who underwent gastric surgery with gastric cancer at the department of surgery, Hanyang university college of medicine from June 1992 to March 2009, we retrospectively evaluated 890 patients with lymph node negative gastric cancer. RESULTS: The lymphatic vessel invasion correlated significantly with tumor stage, age, tumor size, perineural invasion and operation method. The survival rates were only significantly different between the patients with and without lymphatic vessel invasion in patients with stage Ia (P=0.036). Univariate and multivariate analysis demonstrated that blood vessel invasion and preoperative serum CEA level were significant factor influencing the survival rate in lymph node negative gastric cancer patients with lymphatic invasion. CONCLUSIONS: In patients with lymph node negative gastric cancer, the survival rate is significantly lower in those with lymphatic vessel invasion than in those without. Especially, in patients with stage Ia gastric cancer, the survival rates is significantly different between those with and those without lymphatic vessel invasion. Blood vessel invasion and preoperative serum CEA level is an adverse prognostic indicator in patients with stage Ia gastric cancer with lymphatic invasion. Thus we should consider further adjuvant therapies in case of need and need to show more concern to identify gastric cancer patients early at risk for recurrence.
