toasted skin syndrome
A modern condition linked to prolonged resting of hot laptop computers on one’s legs. The relatively high temperatures (115-125ºF/45-50ºC) cause mottling of the skin and pathological changes similar to those seen in solar damage.
Note: Hot laptops are a problem of waning importance, as heat in these devices is typically linked to spinning hard drives, which are being abandoned for solid state drives that operate at lower temperatures. Some new laptops lack cooling fans.
