A painful skin eruption surrounding her colostomy stoma had appeared several months ago and was slowly increasing in size, complained a 64-year-old woman with Crohn's disease. The lesion consisted of several coalescent ulcers with a yellow, fibrinoid base and a violaceous, undermined border.

A painful skin eruption surrounding her colostomy stoma had appeared several months ago and was slowly increasing in size, complained a 64-year-old woman with Crohn's disease. The lesion consisted of several coalescent ulcers with a yellow, fibrinoid base and a violaceous, undermined border. This, writes Dr Gina M. Sevigny of Gainesville, Fla, is pyoderma gangrenosum, an inflammatory skin eruption; it may be associated with an underlying systemic disorder such as Crohn's disease and may flare with the intensity of the bowel disease.

In this case, the pyoderma gangrenosum improved when the patient's Crohn's disease came under good control. It was also managed with oral prednisone therapy and intralesional triamcinolone.
