[Fistula with foreign body granulomatous reaction caused by electrodes left in place after pacemaker removal]

Delayed granulomatous reaction and cutaneous fistula induced by retained electrodes from a cardiac pacemaker in a child

Permanent epicardial pacing wires are sometimes left in place and can lead to long-term complications. We report on a case of a granulomatous reaction with a cutaneous fistula secondary to the retained epicardial pacing wires in a child and highlight the relevance of sonography as an additional tool in the diagnosis and management of dermatologic conditions.

Pacing lead-induced granuloma in the atrium: a foreign body reaction to polyurethane

We described a case of an 82-year-old male who presented with a granuloma entrapping the polyurethane-coated pacing lead at the site of contact on the atrium. He had been paced for 8 years without symptoms or signs suggestive of an allergic reaction to the pacemaker system and died from thrombosis of the superior mesenteric artery and heart failure. A histological examination of the nodule showed an incidental granuloma with multinucleated giant cells. No granuloma was found in the heart or the lung.
