[The primary extranodal manifestation of lympho- and reticulosarcoma of the stomach].

We report about a group of 11 patients with primary lympho- or reticulosarcoma of the stomach in a group of 94 patients with Non-Hodgkin-Lymphomas. There were 5 patients with reticulosarcoma of the stomach among 44 patients with reticularsarcoma (11 percent) and 6 patients with primary lymphosarcoma of the stomach among a total of 50 patients with lymphosarcoma (12 percent). In most instances the diagnosis was made during surgery. At the time of diagnosis only 4 of the 11 patients had Stage IE disease. All patients who received intensive chemotherapy are living. Patients who died during the observation period had reticulosarcomas. They had not received any chemotherapy or treatment was discontinued early for varying reasons. Results are discussed in view of the diagnosis and treatment, suggestions for therapy are made.
