摘　　要：Intro: Primary Sjogren’s syndrome is a chronic systemic autoimmune disease. Although ocular and oral dryness are the hallmarks of this syndrome, renal involvement when present most commonly has the histological appearance of tubointerstitial nephritis and less often glomerular involvement. We report, a unique case of renal manifestations of primary Sjogren’s syndrome with a proven histological focal proliferative and crescentric necrotizing glomeru-lonephritis. Case: A 30 years old man with Kimura disease presented with four months of subjective fevers, migrating skin erythema, dry mouth, and dry eyes. On further workup the patient was found to have a positive ANA, positive anti-SSA, and was evaluated by ophthalmology who found keratoconjunctivitis sicca. The patient was started on hydroxychloroquine in combination with prednisone. On follow up, the patient was found to be hypertensive with acute kidney injury, a creatinine of 3.65, proteinuria and hematuria. Renal ultrasound was unremarkable. Cytoplasmic ANCA was positive and kidney biopsy was performed revealing non pauci-immune focal proliferative and necrotizing glomerulonephritis with cellular crescents and mesangial dense deposits by electron microscopy. Conclusion: To our knowledge, the association between biopsy proven focal proliferative and necrotizing glomerulonephritis with primary Sjogren’s syndrome has never been previously described in the literature, nor has there been a reported case of association between Kimura disease, ANCA serology and primary Sjogren’s syndrome.Intro: Primary Sjogren’s syndrome is a chronic systemic autoimmune disease.
