[Nail changes in rheumatic disease].

Clinically the nail organ ist easy to investigate. When estimating dermato-rheumatological diseases, knowledge of important associated nail symptoms is extremely helpful. In some diseases like osteoarthropathia psoriatica and special variants, Reiter's syndrome and connective tissue disease, typical or even characteristic symptoms can be found. In other disorders like rheumatoid arthritis, goal and systemic vasculitis, associated nail disorders are not uncommon, but of less diagnostic specificity. We review data from the literature and from our dermato-rheumatological outpatient clinic.
