[Nonepithelial tumors of the stomach].

816 patients were operated on because of gastric tumors; in 55 cases they were nonepithelial. Lymphomas have been found in 18 cases, glomus tumors--in 13 cases, leiomyomas, neurinomas and lipomas--in 11 cases, carcinoid--in 7 cases, aberrant pancreas--in 5 cases, gastric wall cyst--in 1 case. In half of the cases tumors were malignant. The preoperative diagnosis was absolutely correct in 30.9% patients and in 61% of cases with gastric lymphomas. All patients with nonepithelial gastric tumors should be operated on. In gastric lymphoma extirpation of the stomach is the operation of choice. In nonmalignant tumors with infiltrative growth and a size not more than 3 cm a stomach resection should be done, in a smaller size--a wedge resection and in subserous small tumors its enucleation, in submucous variant--endoscopic removal is possible.
