Abstract

We report an unusual case of an elderly man presenting with formation and rupture of an epidermal inclusion cyst at the level of an implantable cardiac defibrillator (ICD) pocket. The lesion appeared 2 years after ICD implantation, mimicking a decubitus or a pocket infection. Surgical revision showed no signs of infection of the pocket, but the pedunculated lesion was rooted in the subcutaneous tissue, whit an implant base external to the ICD pocket, which was removed and analyzed histologically, confirming the diagnosis of epidermal inclusion cyst. The pathophysiological mechanism of cyst formation is discussed. This case highlights the importance of an increased attention to lesions that mimic infections of a cardiac implantable electronic device pocket, thus preventing unnecessary complete removal of the device system.

[模仿植入式心脏除颤器袋感染的表皮包涵囊肿:一个罕见的发现]。
我们报告了一例不寻常的病例,一名老年男子在植入式心脏除颤器(ICD)袋水平出现表皮包涵囊肿形成和破裂。病变出现在 ICD 植入 2 年后,类似于褥疮或口袋感染。手术复查显示袋内没有感染迹象,但有蒂的病灶扎根于皮下组织,在 ICD 袋外形成一个植入基底,切除该基底并进行组织学分析后,确诊为表皮包涵囊肿。该病例讨论了囊肿形成的病理生理机制。该病例强调了加强对心脏植入式电子设备袋感染病变的关注的重要性,从而避免不必要地完全切除设备系统。
