* Primary Sjögren's syndrome with chronic tubulointerstitial nephritis and lymphadenopathy mimicking IgG4-related disease.
- We describe a 62-year-old woman with Sjögren's syndrome (SS) presenting with tubulointerstitial nephritis (TIN) and lymphadenopathy mimicking IgG4-related disease (IgG4-RD). Computed tomography revealed multiple swollen lymph nodes. Biopsy of the largest lymph node showed reactive lymphadenopathy with dense IgG4 positive plasma cell (IgG4 + PC) infiltration. Renal biopsy showed chronic plasma cell-rich TIN with IgG4 + PC infiltration. This case suggests that Immunoglobulin G4 immunostaining does not always support the diagnosis of IgG4-RD in the differential diagnosis between SS and IgG4-RD.
