Cystic lung disease is characterised on chest iconography by foci of decreased lung density with definable and thinned walls (wall thickness<4 mm) and with length's diameter superior at 1 cm. Cystic lung disease is exceptionally associated with the Sjögren's syndrome; very few cases have been described.
We report two cases of cystic lung disease associated with Sjögren's syndrome, one occurring in a Lupus-Sjögren's overlapping syndrome, and another revealing primary Sjögren's syndrome.
The Sjögren's syndrome should be recognised as could be associated with Cystic lung disease; and latent Sjögren's syndrome should be researched in presence of cystic lung lesions.
