title: Atypical membranous glomerulonephritis with fibrillar subepithelial deposits in a patient with malignant lymphoma.
abstract: A 61-year-old male treated for a malignant lymphoma developed a nephrotic syndrome. Renal biopsy revealed an atypical form of membranous glomerulonephritis whereby the epimembranous deposits were of fibrillar configuration. Immunoglobulin, kappa light chains and complement were demonstrated in a granular pattern. It is suggested that the fibrillar deposits represent an abnormal structural configuration of immune complex deposits.
