Cutaneous findings in patients with primary Sjogren’s syndrome

Sjogren’s syndrome (SS) is an autoimmune disease that is characterized by exocrine gland involvement. It is reported that the skin is affected in nearly half of SS patients. Cutaneous manifestations consist of xerosis, angular cheilitis, eyelid dermatitis, pruritus, cutaneous vasculitis (frequently manifesting as palpable purpura), and erythema annulare. Most of them are nonspecific and less severe than the oral, ocular, or musculoskeletal symptoms. We present two patients with primary SS who have many cutaneous manifestations including erythema annulare and pernio-like lesions and review the literature about this topic.
