title: Gastric adenomas.
abstract: Thirteen gastric adenomas were found in 11 patients in a series of approximately 11,000 standard biphasic-contrast examinations of the upper gastrointestinal tract (incidence 0.1%). In addition, endoscopy revealed 2 (4-mm) adenomas in one patient who had a negative radiographic examination. Eleven of the 15 adenomas had a maximum diameter that was less than or equal to 20 mm, and 7 lesions had smooth surfaces. These findings are different from those reported in previous North American and European radiological literature. Adenomas have a potential for malignant change, which was found in 4 (greater than or equal to 20 mm) irregularly surfaced lesions in 3 patients (early gastric carcinoma, type I and IIa).
