[Acute renal insufficiency as the first symptom of malignant lymphoma in children].

Acute renal insufficiency in children with malignant lymphoma may be the first symptom of illness. Intensive care with hemodialysis is the therapy of choice. It allows to eliminate the increased volume of liquid, toxins, continuing diagnostic and beginning chemotherapy. We present two children with NHL, who showed acute renal insufficiency. Intensive care with hemodialysis was required to treat renal failure before establishing diagnosis and during initial chemotherapy.
