Early renal involvement in acute lymphoblastic leukemia and nonHodgkin's lymphoma in children.
Clinical manifestations of kidney disease, particularly renal failure, caused by malignant infiltration in patients with acute lymphoblastic leukemia or nonHodgkin's lymphoma have been described rarely. We report 1 case of acute lymphoblastic leukemia and 3 cases of nonHodgkin's lymphoma in which renal disease was the only or one of the presenting manifestations of malignancy. Of these patients 2 had rapidly progressive renal failure with nephromegaly, 1 presented with bilateral abdominal masses caused by severe nephromegaly and with microscopic hematuria, and 1 had microscopic hematuria without nephromegaly. In all 4 patients kidney biopsy revealed malignant infiltration. In the 2 patients who presented with renal failure kidney function promptly returned to normal after chemotherapy and irradiation of the kidneys. Prompt and correct diagnosis of nephropathy, when it is the only or one of the presenting signs of acute lymphoblastic leukemia or nonHodgkin's lymphoma, is necessary to expedite initiation of specific antitumor therapy.
