[Dermatopolymyositis, Gougerot-Sjögren's syndrome, Hashimoto's thyroiditis and glomerulopathy]

We present here a glomerulonephritis in a patient with dermatomyositis, Sjögren's syndrome and Hashimoto's thyroiditis. Glomerulonephritides are rarely described in dermatomyositis and Sjögren's syndrome. Glomerular histology is variable. Nephrotic syndrome and renal failure are not frequent. Moderate doses of corticosteroids produce a rapid improvement.
