[Clinical studies of skin manifestations of Sjögren's syndrome].

The skin manifestations of the patients with definitive Sjögren's syndrome were clinically studied. Chief complaints at the first consultation included annular erythema, pernio-like erythema, Raynaud's phenomenon, purpura, and malar erythema. Drug eruptions and xerotic eczema were also occasionally observed during the course. However, annular erythema, pernio-like erythema, drug eruptions, purpura, facial pigmented patches, and erythema nodosum were observed much more frequently in patients with primary Sjögren's syndrome. These skin manifestations might be useful clues for the diagnosis of Sjögren's syndrome in dermatological fields.
