Boy developed "toasted skin" condition from using a laptop every day
Thursday, September 10, 2026
A boy developed erythema ab igne, a skin condition characterized by a reticulated brown discoloration, after prolonged daily laptop use. The condition results from chronic heat exposure to skin, typically occurring at temperatures between 43 and 47 degrees Celsius over extended periods. Medical case reports document similar presentations in individuals who regularly place laptops directly on their laps or skin for hours daily. The discoloration is often reversible if heat exposure stops, though prolonged cases may result in permanent pigmentation changes.
