Abstract: Celiac disease is an autoimmune enteropathy that can be associated with other autoimmune diseases including igA vasculitis: rheumatoid purpura. We report the case of a patient with celiac disease on a gluten-free diet who developed a rheumatoid purpura clinically suspect and confirmed by anatomopathological study of skin biopsies. Rheumatoid purpura in adults is a rare entity but possible as an association with celiac disease, the pathophysiology involves igA, the transferrin and transglutaminase receptors, the prognosis depends on the renal and digestive system, the treatment is often symptomatic.
