A Case of Pyoderma Gangrenosum After Long Saphenous Vein Harvesting

摘要

IntroductionPyoderma gangrenosum is a rare cause of ulceration that may be confused with post-operative wound infection.ReportA 74-year-old man presented with a painful ulcer after long saphenous vein harvesting. On examination, a 7?×?5?cm ulcer was noted overlying the distal end of the wound. The ulcer had a patchy necrotic base and well-demarcated violet edges with surrounding erythematous, indurated skin. Review of the clinical history revealed previous delayed wound healing. The diagnosis of pyoderma gangrenosum was confirmed by histological analysis.DiscussionThis case highlights the importance of the pre-operative medical history in identifying patients at risk of pyoderma gangrenosum.
