A 90-year-old man presented with a rapidly growing vascular lesion after a pacemaker generator change. The rapid growth suggested a possible angiosarcoma. A less dramatic presentation of vascular proliferation has been described as reticular telangiectatic erythema, which has been reporting following insertion of pacemakers, implantable cardioverter defibrillators, and drug-delivery devices. The onset of the disorder is described as weeks to years after implantation or generator change. It is a benign condition that generally remains static or regresses over time. The vascular proliferation noted in this case resolved almost completely over a period of 1 year.
