There are irregular spaceswhich contain serum and blood cells structed. The appearance of the shadowof the bismuth-filled stomach in a casewith polyp is most suggestive of thepictures seen when there are large massesof food present, or of advanced Fig. 3.

In these spaces thecells spring from the wall in an ele-vated rounded form and have largerounded or oval nuclei. Diagnosis:Lymphangio-endothelioma. The patient made an uneventful re-covery from operation. A month later, atthe time of his discharge, the roentgenray examination showed no evidence ofrecurrence of the mass in the stomach. Themid-portion was somewhat contracted andthe rugae were visible. There was nostasis and no irregularity in peristalsis. SIMMARV Both of these cases had definite pedun-culated tumors. In general, tumors ofthis kind are not malignant. In bothcases the peristaltic waves passed overthe involved area of the stomach withoutevidence of break, such as is seen in lesionswliich involve the gastric wall. When the gr
