Abstract:
Collaboration between specialists is necessary for good practice of medicine. The dermatological examination, mainly based on visual characteristics, can greatly help other specialisms when confronted with a seemingly futile skin anomaly. We discuss the various cutaneous features of some metabolic and infectious diseases, the pitfalls in diagnosing lupus erythematosus without knowledge of skin disease and the relationship of dermatological diseases as cutaneous vasculitis, pyoderma gangrenosum, Sweet's syndrome, pemphigus and more to internal disease.
