The prognosis in such a case is good—even better than that of gastrointestinal carcinoma treated at an early stage. This lesion of the digestive tract is not so rare as commonly thought. Singleton and Moore's collection of reports of gastrointestinal lymphosarcoma up to 1949 lists 563 cases. Its differential diagnosis is difficult.

The other five were lymphosarcomas of the ileum, of the
