British doctors are warning about the risks of prolonged laptop use after a young boy developed a condition known as "toasted skin syndrome" from resting a device on his abdomen for extended periods. The condition, medically termed erythema ab igne, results from consistent exposure to heat that warms the skin but is not hot enough to cause pain or blistering.
Medics from the University Hospitals of Leicester NHS Trust reported the case of a pre-teen boy who would rest a laptop on his stomach for up to eight hours a day, often while it was charging, during home schooling. Initially, doctors suspected a liver injury due to the alarming appearance of the rash. However, blood tests and scans showed no abnormalities. The rash worsened over two weeks, spreading across his stomach and causing peeling skin.
Upon further questioning about his routine, doctors identified the laptop as the cause and diagnosed erythema ab igne. This condition damages tiny blood vessels and fibers beneath the skin, leading to pigment buildup and a net-like rash. Historically associated with sitting near fires or heaters, doctors note its rise in younger individuals due to increased electronic device use.
Experts from the Primary Care Dermatology Society state that mild reactions typically fade over several months after heat exposure ceases. However, more severe skin changes may become permanent. There is also a small long-term risk of developing skin cancer in affected areas, such as squamous cell carcinoma or Merkel cell carcinoma, though such complications can take decades to appear.
Authors of the BMJ Case Reports study emphasized the importance of considering erythema ab igne in children with reticulated rashes, especially given the rise in electronic device usage. Early recognition can prevent misdiagnosis and unnecessary investigations. The boy's family was reassured of the condition's benign nature. He was advised to stop placing the laptop directly on his body, and the rash gradually faded and disappeared completely within months.
This case follows warnings from Japanese doctors last year about "dropped head syndrome," potentially linked to extended smartphone gaming sessions causing neck strain. These instances highlight the emerging health concerns associated with the extensive use of electronic devices by younger generations.
