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.
一位 90 岁男性在更换心脏起搏器后出现迅速生长的血管性病变。快速生长提示可能为血管肉瘤。有文献报道，在心脏起搏器、植入式心律转复除颤器和药物输送装置置入后，也会出现血管增生的不太明显的表现，即网状毛细血管扩张性红斑。这种病变通常在植入或更换发生器后数周至数年内出现。它是一种良性疾病，通常保持稳定或随时间推移而消退。本例中观察到的血管增生在 1 年内几乎完全消退。
