[Osteomalacia revealing Sjögren's syndrome: a case report].
BACKGROUND
The most common renal disease in Sjögren's syndrome is tubulo-interstitial nephritis, responsible for tubular acidosis in around 20 % of patients. Osteomalacia exceptionally occurs as the first manifestation of a renal tubule disorder due to a Sjögren's syndrome.


METHODS
We report a case of a 20-year-old woman with tubular acidosis induced osteomalacia secondary to primary Sjögren's syndrome. Improvement was obtained with bicarbonates, vitamin D, calcium and high-dose steroid therapy.


CONCLUSIONS
During Sjögren's syndrome, osteomalacia can complicate the distal renal tubular acidosis. In spite of the rare cases of osteomalacia revealing Sjögren's syndrome, this auto-immune disease must appear in the list of the aetiologies of osteomalacia.
