Erythema ab igne (EAI) is a dermatological condition characterized by a reticulated, reddish-brown discoloration of the skin. While historically associated with long-term exposure to coal stoves or space heaters, medical professionals are increasingly identifying cases linked to the daily use of personal electronics. The condition develops when heat from devices, such as laptops or tablets, is applied directly to the skin for extended periods.

Recent reports highlight a case involving a young boy who developed the condition after resting his laptop on his stomach for up to eight hours a day. Dermatologists note that while the condition is generally considered benign, it can lead to permanent skin discoloration and, in rare instances, may increase the risk of skin cancer if the heat exposure is not discontinued. The primary treatment involves removing the heat source, which typically allows the skin to heal over time, though the pigmentation may persist for months or years.

Medical experts emphasize that the condition is preventable by ensuring devices are placed on desks or tables rather than directly on the lap or body. As remote learning and digital entertainment continue to occupy significant portions of daily life for children and adults alike, clinicians are urging users to be mindful of the physical proximity of their devices to their skin.
