Rheumatologic conditions

Abstract

Rheumatologic conditions frequently have cutaneous findings, which, in some cases, may be the initial presenting sign of disease. As health care providers, we need to be keenly aware of clues that are manifested on the skin. Rapid recognition and appropriate management of these dermatologic findings can help to improve patient outcomes. This chapter highlights several of the more common rheumatologic conditions that can affect both the cutaneous and renal systems, including systemic lupus erythematosus, Wegener granulomatosis, polyarteritis nodosa, and other vasculitides. Pathogenesis of the skin findings, along with differential diagnoses, recommendations for workup, and therapeutic options, is provided.
