Pyoderma gangrenosum complicating a permanent pacemaker implantation: a case report and literature review

Abstract Background Pocket complications are common after cardiac implantable electronic device implantation. We report a rare case of pyoderma gangrenosum (PG) complicating a permanent pacemaker implantation, and the first literature review of 10 published cases. Case summary Five days after pacemaker implantation for heart failure and 2:1 atrioventricular block, a 93-year-old man had pain in the scar and bleeding on contact. Two days later, he had fever, inflammatory syndrome, and a necrotic 7-cm wound. The pacemaker was removed and he was started on antibiotics. Due to a lack of bacterial growth in samples, PG (a rare aseptic, destructive inflammatory cutaneous condition) was suspected, and histology was compatible with this diagnosis. High-dose corticosteroids vastly improved his condition within 1 week, and after 2 months of decreasing-dose corticosteroid therapy, complete healing and normalization of the inflammatory syndrome were observed. Discussion Pyoderma gangrenosum should be considered if there is aseptic skin ulceration that is not controlled by antibiotic treatment. The first-line treatment for PG is high-dose systemic corticosteroids.
