Pyoderma gangrenosum as a complication of coronary artery bypass grafting.

A 60-year-old male patient developed progressive wound ulcerations, simulating wound sepsis after coronary bypass operation. The condition did not respond to intensive antibiotic therapy. Based on clinical signs and biopsy, the diagnosis of pyoderma gangrenosum was made and successfully treated with cyclosporin A. Pyoderma gangrenosum, although extremely rare, must be considered as a possible diagnosis in wound complications unresponsive to traditional therapy.
