GASTRIC CARCINOID OF SEMI-PEDUNCULATED TYPE -A CASE REPORT-

Abstract

A 67-year-old man was admitted to our hospital for further examination of gastric mass lesion detected at another hospital. Gastric fluoroscopy and gastric endoscopy showed a large elevated lesion on the greater curvature of the upper body of the stomach. Endoscopic ultrasonography (EUS) revealed a sharply bordered hypoechoic tumor measuring 28×14mm in diameter with a heterogenous internal structure, extending mainly within the 3rd layer of the gastric wall. Proximal gastrectomy was performed. Histology confirmed that the tumor consisted of carcinoid tissue extending mainly within the submucosal layer. EUS was a useful method to evaluate location and extension of the tumor in the gastric wall. We have also made a short review of the literature concerning gastric carcinoid of the elevated type.
