Because of their relatively rare incidence, varied morphology, pathology, symptomatology, and roentgen evidence, benign gastric tumors give rise to great clinical interest. That they are more frequent than is generally considered is evidenced by a comparison of the number of benign with the number of malignant gastric tumors examined in the pathologic laboratory which were either removed at operation or discovered at autopsy. At Harper Hospital during the past seven years there have been 12 benign gastric tumors examined in the pathologic laboratory, during which period there have been 266 cases of malignant gastric tumors in the hospital, an incidence of about 4.5 per cent. Hillstrom1found that in the department of pathology of the University of Minnesota, about 5 per cent of all the tumors discovered at autopsy or removed at operation were benign. There have been nearly a thousand cases reported. Pathologically, the benign tumors which have
