Here’s a hazard you probably didn’t expect from too much screen time.
Two doctors in the UK reported in the journal BMJ Case Reports the bizarre case of a young boy whose laptop literally toasted his skin over weeks and maybe even months of using it. Thankfully, the kid’s fine and was never in any real pain, so we can dive into this medical oddity without feeling too guilty about it.
According to the eyebrow-raising paper, spotted by Ars Technica, the boy was first brought into an emergency department with reddish markings over his abdomen in a lace-like pattern. Nurses first described it as “spontaneous bruising,” but they didn’t find skin abnormalities anywhere else on his body. The boy also wasn’t in any pain, and didn’t have any history of trauma or illnesses that could explain the markings.
When doctors did a chest x-ray, they found some kind of build up in his lung, though it was unclear what it signified. The boy admitted that he got pushed into a chair while play-fighting with his siblings a week ago, leading the doctors to search for signs of a traumatic injury. But after a CT scan, they didn’t find any. They weren’t completely sure of what was going on, but the doctors discharged him with antibiotics for a suspected lung infection.
The boy was back several weeks later, though — and the rash was even worse. Parts of his abdomen were pinkish, exhibiting clear signs of skin breakdown, the doctors wrote, with mottled patches of dark brown. (You can view a photo, at your own peril, here, via Ars.)
That’s when the doctors began to suspect some kind of heat damage. But when they asked the boy about heat sources, nothing turned up.
Then, as they continued to question him, the boy mentioned something crucial: he was home-schooled and did most of his assignments on his laptop, sometimes for eight hours a day, often while charging. And of course, he usually rested the laptop on his torso while lying down.
This supported a diagnosis of a erythema ab igne (EAI), also known as “toasted skin syndrome.” It’s caused by repeated, close exposure to low heat, which slowly damages the skin over time. Patients often get it from heat pads and space heaters, but a warm laptop can cause it, too. It causes a distinctly lace-like rash, which explained the boy’s symptoms.
EAI is benign, and in most cases, its rashes disappear on their own once exposure to a heat source is stopped, taking weeks to months to heal. Once properly diagnosed, the boy’s rash was dressed, and he came back to the hospital several months later to confirm that he had fully healed. Now that he’s okay, he might try studying at a desk instead.
