Toasted skin syndrome refers to a skin rash caused by lengthy exposure to a heat source, such as laptop computer balanced on the thighs for an extended period. That is why it is also called laptop thigh.

“烤肤综合征”指因为长期接触热源导致的皮肤出红疹症状，长时间把笔记本电脑放在大腿上操作是该症状的常见诱因之一，因此该症状也被称为“笔记本电脑腿”。

For example:

Have you ever worked on your laptop computer with it sitting on your lap, heating up your legs? If so, you might want to rethink that habit. Doing it a lot can lead to "toasted skin syndrome".

你是不是曾经把笔记本电脑放在腿上工作，大腿还能感受到电脑发热？如果是这样，你可能要重新考虑下这样的做法了。长期把笔记本电脑放在腿上工作会导致“烤肤综合征”。
