Presented are the clinical and pathologic features of ten cases of malignant lymphoma and one case of plasmacytic myeloma, in all of which unilateral renal localization was apparent clinically and pathologically. The subsequent course of the lymphoma cases, in which nine of the patients developed disseminated tumor, cast doubt on this appearance. The most frequent histologic type was reticulum-cell sarcoma and the gross pattern of renal involvement was predominantly hilar, nodular parenchymal, or diffusely infiltrative. The long-term survival after nephrectomy in the case of plasmacytic myeloma indicates primary renal origin of that tumor.
