Splenic lymphoma presenting as necrotizing glomerulonephritis.
The authors report a case of necrotizing glomerulonephritis, with granular immune deposits, leading to the etiologic diagnosis of splenic non-Hodgkin's Lymphoma (NHL). The serum creatinine, initially markedly elevated, decreased under steroids and chlorambucil. Unfortunately, the patient died from septic complications. The importance of a careful search for a (localized) NHL in case of necrotizing glomerulonephritis with granular immune deposits is emphasized.
