Retiform purpura, a diagnostic-therapeutic challenge

Abstract

Cutaneous involvement is frequent and heterogeneous in autoimmune diseases. In some of them, such as in systemic lupus erythematosus, dermatomyositis, systemic sclerosis and antiphospholipid syndrome, some manifestations are so relevant that are included in the classification criteria. Differential diagnosis ranges in severity. Since the disease may be life-threatening, a prompt diagnosis and treatment are mandatory. We describe a clinical case of a twenty-two-year-old woman with diagnosis of systemic lupus erythematosus and antiphospholipidic syndrome, presenting with acute, painful cutaneous lesions with necrotic aspect, fever and livedo reticularis.
