[Ulcerative colitis associated with pyoderma gangrenosum].

The authors present a 42-year-old man's case in whom the onset of chronic ulcerative colitis and pyoderma gangrenosum was simultaneous. Pyoderma gangrenosum began as bullae on his chest and lower limb. The main symptoms were fever, anaemia, hypoproteinaemia beyond the skin lesions, and the abdominal symptoms characterizing chronic ulcerative colitis were absent. The thorough internal check-up and the micribiologic and histologic examinations of the skin disorders made clear that the lesions mentioned were the skin symptoms of a systemic disease. Sulfasalazin and prednisolone therapy of the underlying disease and the local non-specific treatment of the cutaneous lesions resulted together in the patient's rapid improvement. The authors give a brief review of pyoderma gangrenosum and of the connection between pyoderma gangrenosum and chronic ulcerative colitis.
