Glomerulonephritis is the common manifestation of SLE and occurs in approximately 60-75% of patients. However, renal involvement as an initial presentation of SLE is not frequent finding. Serum complement levels and anti-ds DNA titer are useful tests in assessing the activity of lupus nephritis, but the level of anti-ds DNA is often normal in patients with pure membranous disease. With the above characteristics, this case shows atypical serology that is positive anti-La/SSB which is related with the absence of nephritis.
