A Case of Multiple Gastric Carcinoids Associated with Chronic Atrophic Gastritis and Hypergastrinemia / 대한소화기내시경학회지

ABSTRACT

Gastric carcinoid tumors are so rare that they constitute less than 1% of total primary gastric tumors. They are classified into 3 types: (1) gastric carcionoid associated with chronic atrophic gastritis (type I), (2) gastric carcinoids associated with Zollinger-Ellison syndrome (ZES) or multiple endocrine neoplasm (MEN) type 1 (type II), and (3) sporadic gastric carcinoid (type III). A 55-year-old man underwent a medical check-up. Five polypoid masses were incidentally detected in the cardia, fundus and midbody whose size ranged from 0.5 cm to 1.6 cm in diameter. Tumor cells were strongly positive for cytokeratin, synaptophysin and chromogranin staining. Biopsies from the body and fundus showed severe atrophy. Fasting serum gastrin level was highly increased, 1,098 pg/mL. There was, however, no evidence of the presence of ZES or MEN type 1. The patient underwent total gastrectomy for complete resection and has remained free of any complications with normal serum gastrin level.
