Examination of the skin and oral mucosa may show mucocutaneous or aphthous ulcers, erythema nodosum, and pyoderma gangrenosum. Skin examination may also reveal pallor in patients with anemia or jaundice in those with concomitant liver disease with cholestasis. Eye examination may reveal episcleritis. For the diagnosis of uveitis, a slit-lamp examination by an experienced physician is necessary.
