Intracardiac Masses Associated With Permanent Endocardial Pacemaker Lead Erosion Through the Skin

摘要

A72-YEAR-OLD, 178-cm, 57-kg man presented to the authors' institution with an exposed permanent endocardial pacemaker lead adjacent to an old left subclavian pacing generator pocket. The patient reported that a "cystic" swelling began over the old generator site approximately 4 months before admission. The pacemaker lead eroded through the skin 2 months later, but the patient had only recently sought medical attention for an unrelated problem. He denied fevers, chills, or drainage at the wire-erosion site. The patient had a 16-year history of complete heart block.
