Abstract:
Recently, a case report published in a medical journal attracted attention. A British boy suffered from skin damage called "roasted skin syndrome" after putting his laptop directly on his abdomen for long periods of time while studying. Doctors point out that although laptops usually do not generate high temperatures that can cause burns, long-term and repeated exposure to lower-intensity heat sources may still cause damage to the skin.
According to reports, the boy, who is in middle childhood, was rushed to the hospital emergency room because of abnormal plaques on his abdomen. Doctors observed that a flat reddish-brown reticular pattern appeared in an area about 15 cm wide on his abdomen, with irregular rings and lace-like structures. Oddly, the affected area was neither painful nor significantly warm or tender. Both the boy and his parents stated that there was no obvious recent trauma or illness that could explain these skin changes, and that the child's overall health, development, and past medical history were normal.
Emergency paramedics initially suspected it was some kind of "spontaneous bruising." During a physical examination, doctors found no other skin abnormalities, abdominal tenderness, or signs of organ damage. Upon further examination, a chest X-ray showed a small abnormal shadow in the left lung area, suggesting that there may be local cell accumulation or fluid accumulation, such as pus or blood.
During a subsequent blood test, the boy mentioned that about a week earlier, around the time the skin marks appeared, he had been pushed into a chair while playing with his siblings. He had not taken the initiative to mention the matter before, fearing his siblings would be blamed. Based on this, the doctor suspected that there might be potential trauma, so a CT examination was performed to rule out internal abdominal injuries. The results showed that except for the slight imaging abnormality in the lungs, no relevant damage was found; the lung abnormalities may also be just incidental findings caused by mild infection.
Since a clear cause could not be found, the doctor finally sent the boy home for observation and gave him short-term antibiotic treatment to deal with possible lung infections. Parents were also advised to pay close attention to changes in the condition and seek medical attention again if the skin problem persists or worsens.
Two weeks later, the boy returned to the hospital. At this time, the abdominal plaques worsened significantly, further expanded in area, became darker in color, and began to become tender. Some areas showed pink patches and skin breakdown. Faced with the progression of the disease, the doctor re-examined the previous diagnosis direction and conducted more in-depth inquiries about the boy's daily habits.
During the consultation process, the boy revealed that he received home education and needed to use a laptop for a long time to complete course studies. He is used to operating the computer directly on his abdomen, sometimes for up to eight hours a day, and often works while the computer is connected to a power source for charging. At this point, the doctor finally found the real cause.
The doctor finally diagnosed him with "erythema abigne," whose medical Latin name is Erythema ab igne, commonly known as "roasted skin syndrome." This disease is not caused by high-temperature burns, but by repeated long-term exposure of the skin to lower-intensity heat sources. Cases are more common in adults, and common triggers include long-term use of heating pads, hot water bottles to relieve chronic pain, or prolonged proximity to heaters. Some special occupational groups, such as glass blowers and metal processing practitioners, may also experience similar situations. The typical manifestation is a reticular, lace-like reddish-brown rash, which is highly consistent with the boy's symptoms.
At present, the medical community has not fully understood the specific formation mechanism of this disease. But the researchers speculate that continued heat exposure may damage superficial blood vessels in the skin and cause red blood cells to leak out, creating the characteristic reticular erythema pattern.
Although the appearance of the lesions may be alarming, doctors say that erythema pyrotechnica is usually a benign condition and most patients can recover as long as the heat source is removed promptly. In more severe or longer-lasting cases, some pigmentation and scarring may remain. According to follow-up results, after the boy stopped using the drug, the rash on his abdomen gradually subsided over several months and eventually returned to normal.
This case once again reminds the public that although electronic devices usually do not reach temperatures that can cause acute burns, direct contact with the skin for a long time, especially when the device is continuously working and charging, may still bring overlooked health risks.
