A CASE OF COMPOSITE GASTRIC CARCINOID AND EARLY GASTRIC CANCER IN TYPE A GASTRITIS TREATED WITH ENDOSCOPIC SUBMUCOSAL DISSECTION

Abstract

A 69-year-old man was referred to our department with a gastric tumor which was detected during a medical checkup. Upper gastrointestinal endoscopy showed a gastric tumor with epithelial change in the greater curvature. Endoscopic submucosal dissection (ESD) was performed because early gastric cancer was suspected. Histopathological examination of the resected specimen confirmed the diagnosis of composite gastric carcinoid and early gastric cancer with endocrine cell micronests for a background. In addition, type A gastritis was confirmed on the basis of blood chemical analysis and endoscopic findings. We present herein on this case treated with ESD, considering its possible rarity.
