초록

Secondary rapidly progressive glomerulonephritis (RPGN) can be caused by many diseases and conditions, including vasculitis,systemic rheumatic diseases, infections, drugs and malignancies. Among the secondary RPGNs, malignancy-associated RPGN isextremely rare and causes renal function deterioration within several weeks to months. Thus, timely immunosuppressant therapycan improve renal outcome. Herein, we describe a case of RPGN detected simultaneously with marginal zone B-cell lymphoma. An82-year-old male patient, who presented generalized edema and oliguria, was diagnosed with crescentic glomerulonephritis andmarginal B-cell lymphoma. After the patient was given methylprednisolone pulse therapy, renal function was restored and hemodialysiswas successfully discontinued without complications.
