Lymphosarcoma of the stomach is not a common neoplasm and in the great majority of cases is not diagnosed before operation. According to Ewing, lymphosarcoma of the stomach constitutes about 1% of malignant gastric lesions.
The number of reported cases of lymphosarcoma simulating gastric ulcer is small. Cabot, in 1933, reported two cases. One case was incorrectly diagnosed clinically as gastric ulcer and carcinoma of the stomach, while the second case was correctly diagnosed as lymphoblastoma of the stomach with ulceration.
Koucky, Beck, and Atlas reported a case of acute perforation of a lymphosarcomatous ulcer of the stomach which was diagnosed by biopsy at the time of operation.
Pack and McNeer emphasize the point that patients with lymphosarcoma of the stomach not infrequently present a typical ulcer pain history with x-ray studies showing an ulcer. Perforation of ulcerating lymphosarcoma is more frequent than in carcinoma, according to these writers. In
