Arthritis and skin disease

Abstract

Skin lesions are frequently a harbinger of an underlying rheumatic disease or may be of great help in achieving the diagnosis of an underlying joint or connective tissue disease. For this reason, the evaluation of the skin is mandatory for the rheumatologist. In fact, the skin is the most accessible organ and often provides valuable diagnostic clues. Pattern recognition of skin lesions is based upon the type, configuration, distribution, and evolution of the lesions; selective laboratory techniques may further assist the diagnosis. This article focuses on the most relevant cutaneous disease in patients with rheumatic disease and emphasizes those characteristic features that will allow the clinician to identify cutaneous lesions that are commonly associated with musculoskeletal syndromes.
