RESUMO
BACKGROUND: Rheumatoid arthritis is one of the most common autoimmune disorders. In addition to chronic arthritis, rheumatoid arthritis may present a variety of extra-articular manifestations, most commonly of the skin. OBJECTIVES: Cutaneous manifestations associated with rheumatoid arthritis can be diverse, both specific and nonspecific. Which dermatoses should lead you to the diagnosis of an underlying rheumatoid arthritis? METHODS: Evaluation of exemplary overviews, case presentations and relevant textbook articles. RESULTS: Rheumatoid arthritis presents various specific and nonspecific skin manifestations. Besides visual diagnosis like classic rheumatoid nodules a histopathologic correlation or an interdisciplinary approach is often needed, such as for diagnosis of pyoderma gangrenosum. CONCLUSIONS: The early detection and correct classification of cutaneous manifestations associated with rheumatoid arthritis can be groundbreaking for a successful therapy and a consequently better prognosis for patients with rheumatoid arthritis. Therefore dermatologists bear responsibility in the patient-centered care.
