Fourteen cases of primary malignant lymphomas of the breast were found in the pathology files of the M. D. Anderson Hospital and Tumor Institute from 1944 to 1975. ⋯ Patients with histiocytic lymphoma appeared to have a more favorable prognosis than those with the undifferentiated type. Six of the latter patients are dead with a median survival of seven months, comparable to the reported survival of patients with American Burkitt's lymphoma. The patient with the convoluted cell type has developed acute blastic leukemia and is currently under therapy.
