The prevalence of fibromyalgia in primary (n = 18) or secondary (n = 20) Sjögren's syndrome was examined. In all patients with Sjögren's syndrome as well as in 31 fibromyalgia patients and 20 healthy individuals measurements of pressure pain threshold were done by palpation and dolorimetry. Widespread pain, functional complaints, as well as depression were determined by a questionnaire. ⋯ The results suggest to include Sjögren's syndrome into the differential diagnosis of FM. The dolorimetric results were interpreted as an argument against the actual tenderpoint concept. They support the view that patients with FM rather represent an arbitrary coincidence of widespread pain and elevated tenderness on pressure.
