A 76-year-old man developed progressive blanchable reticulate erythema at the implantation site of his third implantable cardioverter defibrillator (ICD). Despite reports of allergic contact dermatitis to implantable devices, extensive routine patch testing in our patient failed to identify a responsible allergen. The clinical presentation and pathologic evidence were consistent with reticular telangiectatic erythema that has been reported overlying pacemakers and, in the English literature recently, overlying ICDs in two patients. Reticular telangiectatic erythema is a benign reactive condition that is possibly due to a combination of aberrant local circulatory and physical forces such as heat, electric fields, or magnetic fields.
一名76岁男性在其第三个植入式心脏复律除颤器（ICD）的植入部位出现了进行性可褪色的网状红斑。尽管有报告称对植入式设备存在过敏性接触性皮炎，但对我们这位患者进行的广泛常规斑贴试验未能确定相关过敏原。临床表现和病理证据与网状毛细血管扩张性红斑相符，这种红斑曾被报道出现在起搏器上方，最近在英文文献中也有两例出现在ICD上方的报道。网状毛细血管扩张性红斑是一种良性反应性病症，可能是由局部循环异常和诸如热、电场或磁场等物理力共同作用所致。
