title: [Petechiae, microhematuria, colic-like abdominal pain].
abstract: A 46-year-old patient was referred because of recurring bouts of abdominal colics, petechiae and an accompanying nephropathy. The clinical setting pointed towards a cryoglobulinemia, proved by serum cryoprecipitation and electrophoresis and classified as type II. The primary disease was a low-grade non-Hodgkin lymphoma involving bone-marrow and liver. A renal biopsy showed a proliferative glomerulonephritis. Treatment with prednisone and chlorambucil led to improvement of renal function, and the patient became asymptomatic.
