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.
