Interstitial Cystitis: An uncommon revelation in primitive Sjögren syndrome.

Interstitial cystitis is an exceptional entity during primary Sjögren's syndrome. In this regard, we report the case of a 67-year-old patient in whom initially idiopathic interstitial cystitis revealed primary Sjögren's syndrome after 5 years of evolution in front of xerostomiaa, xerophtalmia and bilateral parotid hypertrophy with histological confirmation at the biopsy of accessory salivary glands.
