ABSTRACT
A double pylorus, a fistulous communication between the gastric antrum and duodenal bulb, is a very rare anomaly. It appears as an acquired lesion in the majority of cases and mainly occurs in males with chronic obstructive pulmonary disease, chronic renal failure, chronic rheumatism, systemic lupus erythematosus, or diabetes. However, there are no previous reports of a double pylorus combined with diabetes mellitus in Korea. Recently we experienced a case of double pylorus caused by a peptic ulcer in 74-year-old man who had diabetes mellitus with complications. We report this case with a review of the literature.

A carcinoid tumor is a slow growing, rare neoplasm arising from enterochromaffin cells with a malignant potential. A primary carcinoid tumor of the stomach and duodenum is uncommon. However, their prevalence has been increasing due to the widespread use of endoscopy. Recently, the use of endoscopic resection for the treatment of small carcinoid tumors is gradually increasing. To our knowledge, this is the first case report of synchronous carcinoid tumors in the stomach and duodenum. We report a case of small, multiple carcinoid tumors of the stomach and duodenum in a 58-year-old man that was endoscopically removed with a snare.

Granular cell tumor (GCT) is a relatively rare benign tumor that can be located anywhere throughout the body, but it is uncommon in the gastrointestinal tract, and especially in the colon and rectum. A 41-year-old man visited our hospital with a three-month history of intermittent abdominal discomfort at the left lower quadrant area. Colonoscopic examination revealed a hemispheric, submucosal lesion, about 1.5 x 1.2 cm in size, on the opposite side of the ileocecal valve in the proximal ascending colon. The tumor was removed by an endoscopic snare without any immediate complication. The pathologic findings revealed spindled or polygonal large cells that were positive for S-100, neuron-specific enolase and vimentin, and they were negative for smooth muscle actin and desmin, which was consistent with granular cell tumor. We report here on a case of granular cell tumor of the colon that was successfully treated with endoscopic polypectomy.
