Lupus nephritis in an anti-nuclear antibody-negative young male. The simultaneous presence of class III and class V renal lesions.
We report about a 27-year-old white male, a known case of class III lupus nephritis with a very high anti-nuclear antibody (ANA) titer, who after 10 years of complete clinical and serological remission presented with sudden development of malar rash, proteinuria and an increase in the serum creatinine. Repeated serologic studies were all negative for ANA. A repeat kidney biopsy disclosed the presence of focal segmental glomerulosclerosis lupus nephritis (class IIIc) superimposed with a new membranous lupus nephritis (class V).
