Laptop heat leaves rash
A boy in the UK was brought to the emergency department with what doctors described as “spontaneous bruising” on his abdomen, but he had no trauma, no abnormal bloodwork, and no obvious explanation.
In the case report published in BMJ Case Reports, clinicians later learned that the boy had been resting a laptop on his stomach for up to eight hours a day, often while it was charging, placing the device directly on bare skin.
The diagnosis was erythema ab igne, also called toasted skin syndrome, described as a condition caused by repeated exposure to low-level heat that never burns but quietly damages skin over weeks and months.
Dr. Mara Znagoveanu of University Hospitals of Leicester NHS Trust said, “The increasing use of electronic devices, particularly during home-schooling, has emerged as an under-recognised cause of EAI in paediatric populations.”
After the boy stopped resting the laptop on his stomach, the rash resolved, and a phone call with his father later confirmed the skin had vanished.
Misdiagnosis and targeted history
The initial workup included scans showing no internal trauma and blood tests that came back normal, but the rash worsened two weeks later into a tender, peeling, spreading pattern. In the University Hospitals of Leicester case, the boy’s family initially couldn’t identify any hot water bottles or space heaters, and the doctors’ questioning eventually focused on the laptop he kept on his abdomen. New Atlas reported that the authors, GP Mara Znagoveanu and paediatrician Edward Artley, concluded, “Early recognition through targeted history-taking can prevent misdiagnosis and avoid unnecessary investigations,” in their BMJ Case Reports study.
Manchester Evening News also quoted Znagoveanu saying, “The increasing use of electronic devices, particularly during home schooling, has emerged as an under-recognised cause of EAI in paediatric populations.” The case was framed as a warning that without asking about heat exposure from devices, clinicians may order unnecessary tests and miss the cause.
What’s at stake next
The reporting around the case emphasizes that toasted skin syndrome is usually reversible once the heat source is removed, with the rash normally improving over weeks to months after exposure stops. However, the sources also describe longer-term risks, including persistent brown hyperpigmentation and rare cases where long-standing severe disease has been associated with skin cancer risk. Gadget Review | Western Alternative warned that “Laptop surfaces can reach temperatures around or above 113°F during heavy use or while charging,” placing children within the range where the condition develops with chronic exposure.
The Guardian’s discussion of the medical warning also pointed to the need for awareness, quoting Clean Clothes Campaign spokesperson Ineke Zeldenrust about audits, but the relevant medical stakes in this case were framed by the lack of formal pediatric guidelines for EAI. In the end, the practical fix described across the accounts is behavioral: keep the laptop off bare skin, avoid resting a charging device directly on the body, and use a desk, a lap desk, or a thick book to break direct skin contact.
