Three years ago I1reported roentgenologic observations in twenty-three cases of benign tumor of the stomach in which operation was performed at the Mayo Clinic. Since then eighteen additional cases have been observed here. It is my purpose to recapitulate the amplified series and review the subject. A survey of the literature has disclosed fifty-two cases recorded by others, and the aggregate thus affords a reasonably substantial basis for certain general deductions. As compared with malignant new growths, benign tumors of the stomach are rare. Various compilations, derived from necropsy and surgical statistics, have been made to determine their incidence. Eusterman and Senty2have computed that only 1.3 per cent of all gastric tumors seen at operation are benign. However, this percentage does not represent their practical importance, for the diagnosis in a given instance may have an individual significance which cannot be measured by statistics. Histologically, the
