Sarcoma of the Stomach

In recent years there has been a considerable increase in the number of reports of cases of sarcoma of the stomach. It is the purpose of this study to add several cases to the literature and emphasize some of the pathologic features of the disease. The term primary lymphosarcoma of the is confusing and requires clarification. It is generally agreed that lymphosarcoma is a systemic disease which may manifest itself in many different ways. If it appears in the stomach this is merely the site of local involvement. Unlike carcinomatous lesions, which form more or less definite patterns depending on the organ involved, lymphosarcoma is essentially the same regardless of the tissue in question. Like carcinoma it is malignant and spreads by continuity and contiguity and metastatically. Morgagni 1 first described the condition in 1751. Sibley 2 in 1856, Bruch 3 in 1847 and Cruveilhier 4 in 1871 each
