Annular elastolytic giant cell granuloma after a cardiac pacemaker implantation

Abstract

Annular elastolytic giant cell granuloma (AEGCG) is an uncommon condition belonging to the family of elastolytic granuloma, which also includes actinic granuloma, atypical necrobiosis lipoidica of the face and scalp, and Miescher's granuloma.1 Classification of AEGCG as a distinct entity has been controversial. Although some consider it synonymous with actinic granuloma, a term often used interchangeably with AEGCG in the literature, others regard elastolytic granulomas as a variant of granuloma annulare.2, 3 These controversies exist largely because the etiology and pathogenesis of AEGCG is still unknown. Here we describe an unusual case of AEGCG that developed after a cardiac pacemaker implantation. The circumstances that surrounded the eruption of our patient's rash may suggest that trauma is a possible trigger for AEGCG.
