title: A case with membranous lupus nephritis developing after a twenty-year remission of membranoproliferative glomerulonephritis.
abstract: A 30-year-old woman who showed remission of membranoproliferative glomerulonephritis (MPGN) 20 years previously developed membranous lupus nephritis (MLN). She had photosensitivity, facial erythema, proteinuria of 2.59 g/24 hr, anti-nuclear antibody and anti-ds-DNA antibody. To confirm whether a misdiagnosis of MPGN was made 20 years ago, the clinical data at that time were evaluated retrospectively. She had only mild proteinuria and hematuria but no photosensitivity or facial erythema. Anti-nuclear antibody was negative. Renal biopsy showed occasional lobulation and glomerular capillary double contour. The diagnosis of MPGN was definite. This might be a rare case of one person suffering from two types of glomerulonephritis, MPGN and MLN.
