[Lymphocytic colitis and Gougerot-Sjögren syndrome. Report of two cases].

INTRODUCTION: Microscopic colitis describes a subset of patients with chronic watery diarrhea of unknown origin, and normal endoscopic findings and microscopic evidence of an inflammatory infiltrate in the colonic mucosa. We report two cases associated with sicca syndrome. EXEGESIS: A 56-year-old woman and a 76-year-old man presented with a history of lymphocytic colitis associated with sicca syndrome. Drugs or infectious agents were not implicated in the cause of lymphocytic colitis, suggesting that sicca syndrome may be involved in the pathogenesis of microscopic colitis.
CONCLUSION: These cases suggest that sicca syndrome should be detected in patients with lymphocytic colitis.
