Abstract

Patient is an 82 years old male with a chief complaint of chest disturbance and vomiting. Gastroendoscopy was performed and erupting nodule was detected on gastric antral wall, suspicious of submucosal tumor. Biopsy showed Group 1 study. CA19-9 and CEA was both positive, and thickening of antral wall was shown on abdominal CT with contrast. Repeat biopsy showed no malignancy. EUS-FNA was performed, and biopsy specimen showed Group 5 to confirm malignancy.Therefore, EUS-FNA may be considered to be the next tool for diagnosis.
