A Case of a Gastric Submucosal Lymphatic Cyst Associated with Early Gastric Cancer / 대한소화기내시경학회지

A lymphatic cyst of the stomach is rare benign tumor which is composed of thin-walled lymphatic space lined by benign-appearing endothelial cells. It rarely manifests clinical symptoms, so it is found incidentally in most cases. Recently, a case of submucosal lymphatic cyst associated with early gastric cancer was experienced. An endoscopy revealed a slightly elevated, edematous lesion adjacent to the malignant ulcer. This case is herein reported with a brief review of related literature.

A Case of Gastric Hyperplastic Polyposis Associated with Colonic Hyperplastic Polyposis / 대한소화기내시경학회지

Gastric polyps are uncommon. The incidence of gastric polyps has been reported between 0.4% and 2.0%. Two histologically distinct forms of gastric polyps are hyperplastic polyps and adenomatous polyps. Hyperplastic polyps are multiple in up to a half of cases. When the polyps number is more than 50, the term "Hyperplastic polyposis" is applied and such cases are even more rare. Polypoid lesions of the stomach have heen reported in many of the polyposis syndromes, such as Familial polyposis coli, Gardners syndrome, Peutz-Jeghers syndrame, Juvenile polyposis and Cowdens disease. Only 1 case of gastric hyperplastic polyposis associated with colonic hyperplastic polyposis has been reported. The patient under study is not included in any polyposis syndrome and has no familial tendency, We report a case of gastric hyperplastic polyposis with colonic hyperplastic polyposis with literatures reviews.
