ResumoGASTRIC NEOPLASMS are by no means rare. Marshall and Adamson 1 reported 2,014 tumors of the stomach seen at the Lahey Clinic over a 27-year-period from 1932 to 1958.

The vast majority of these tumors in the above two series were malignant; carcinoma was the most frequent finding, comprising 72% to 92% of the tumors, respectively. Benign gastric tumors accounted for 4.8% and 16.9%.

Types of benign tumors seen were leiomyomas, adenomatous polyps, gastritis polyposa, pancreatic
