Cutaneous purpura of Sjögren syndrome successfully treated with hydroxychloroquine

Sjögren syndrome is a systemic autoimmune disease characterized by dry eyes (keratoconjunctivitis sicca) and dry mouth (xerostomia). Common cutaneous manifestations of Sjögren syndrome include xerosis, annular erythema, hypergammaglobulinemic purpura, and immunologic inflammatory conditions such as vasculitis (leukocytoclastic and urticarial).1 The clinical manifestations of vasculitis depend on the degree of skin and blood vessel involvement and can range from petechiae to palpable purpura and widespread ecchymoses.
