Erythema ab igne (EAI) is a persistent chronic skin condition that is characterized by reticulated macular hyperpigmented lesions caused by repeated exposure to infrared radiation. EAI has reemerged in recent years because of the increasing infrared exposure due to the use of new technologies, such as portable computers and automobile seat heaters. We report a case of a 54-year-old female patient presenting with asymptomatic mottled brownish plaque on both sides of her neck for 1 month prior to the visit. Patient history revealed uiat she had used a home skincare device for skin rejuvenation and relaxation. The clinicopathological features suggested a diagnosis of EAI. To our knowledge, mere has only been one reported case of EAI on me neck related to a thermal pillow, and diis was the first case of EAI related to the self-skincare devices. Herein, we report a rare case of EAI presenting on both sides of me neck due to the use of a modem home skincare device.
