Primary malignant lymphoid tumors of the stomach

Abstract

AI ICNANT neoplasms of the stomach that M arise iiom mesodernial elements are much less comnion than malignant neoplasms of entodermal origin. Various clmicsla 3 , have reported that 1.5 to 3.2 per cent of malignant gastric lesions are saicomai. However, Rlar - shall2 found only fifty-one cases of saiconia among 1618 malignant gastric neoplasms and reported that thirty-five were 01 lymphoid origin. During a twenty-three-yea1 period, 1932 to 1955, forty-fom gastric sarcomas have been encountered on the pavilion seilite of T h e New York Hospital, and thirty-two of these arose from lymphoid elements. Six hundred one malignant lesions of the stomach were treated during this same period. Thus, malignant lymphoid neoplasms reprewnt approximately 5 per cent of the malignant gastric lesions in this series.
