British doctors are issuing a warning about the potential for a disfiguring skin condition, known as 'toasted skin syndrome,' resulting from prolonged contact with heat-emitting electronic devices.
The condition, medically termed erythema ab igne, develops when skin is exposed to heat that is not hot enough to cause an immediate burn but is sufficient to damage small blood vessels and fibers beneath the skin. This damage can lead to pigment buildup and a distinctive, fishnet-like rash.
A case report published in the journal BMJ Case Reports detailed how a pre-teen boy developed the condition after resting a laptop on his abdomen for up to eight hours daily during home schooling. He would often use the device while it was charging.
Initially, doctors suspected a liver issue due to the rash's appearance. However, blood tests and scans were inconclusive. The boy returned to the hospital two weeks later with a worsened rash that had spread and begun to peel.
Upon further questioning about his daily routine, the connection to laptop use emerged. Doctors diagnosed the condition as erythema ab igne, emphasizing the link to consistent heat exposure.
Historically, erythema ab igne was associated with prolonged exposure to heat sources like open fires or hot water bottles. However, medical professionals note an increase in younger individuals experiencing the condition, attributing it to the widespread use of electronic devices.
While mild cases of toasted skin syndrome typically fade over several months after heat exposure ceases, more severe or persistent changes may remain. Experts also caution about a small, long-term risk of developing certain skin cancers, such as squamous cell carcinoma and Merkel cell carcinoma, in areas repeatedly affected by the condition. These complications can take decades to manifest.
The authors of the case report stressed the benign nature of the boy's condition and reassured his family. He was advised to cease resting the laptop directly on his body and avoid further heat exposure to the affected area. Months later, his father reported that the rash had completely disappeared.
Medical professionals are urging greater awareness of this condition and the importance of avoiding prolonged direct contact between electronic devices and the skin. They highlighted the need for early recognition of erythema ab igne in children presenting with reticulated rashes, especially given the rise in electronic device usage.
This case follows other health concerns linked to extensive screen time, including 'dropped head syndrome' previously warned about by Japanese doctors in relation to long smartphone gaming sessions.
