Inflammatory gastrointestinal disorders (ulcerative colitis and Crohn's disease) are often associated with cutaneous disorders, which occasionally may even precede the internal symptoms. Aside from the specific skin diseases, such as erythema nodosum or pyoderma gangraenosum, a number of unspecific skin eruptions may be found in both disorders. Here we report on 2 cases of ulcerative colitis associated with granulomatous rosacea.
