[Para-amyloidosis in 2 patients with malignant diseases].

Two cases are described with paraneoplastic amyloidosis, advancing in patients with a basic etiological moment--myeloma and hypernephroma. The clinical picture, in both patients was dominated by the nephrotic syndrome and rapidly progressing renal insufficiency, leading to the fatal end within a very short term. That term in the patient with hypernephroma was only several months after making the diagnosis, and in the patient with myeloma--up to two years. Renal punch biopsy was performed to both patients during their life time.
