Association of Gougerot-Sjögren syndrome and pulmonary adenocarcinoma: A case report

Interstitial lung disease represents the primary pulmonary involvement in Sjögren's syndrome. A number of patients with Sjögren's syndrome develop a progressive fibrosing form of interstitial lung disease, but there is no data on the prevalence of such presentations. The incidental association of malignant tumors has been described independent of any therapy. We report a case of a patient with chronic interstitial lung disease at the fibrosis stage secondary to Sjögren's syndrome, in whom bronchoscopy incidentally revealed metastatic pulmonary adenocarcinoma.
