Sjogren's syndrome: implications for the primary care physician.

Sjogren's syndrome (SS) is a common immunologically-mediated disorder that will afflict a great proportion of our population in future years. The primary care physician undoubtedly will be confronted with such patients, many of whom will have complaints and findings not generally believed to be due to SS. In this communication, case reports of four patients with SS as well as a literature review are presented. Two patients had presentations that were classic for SS; however, the other two were diagnostic challenges. Emphasis is placed on the atypical and unusual way SS can present so that the primary care physician can more easily make the diagnosis and initiate therapy.
