Freud had this wonderful phrase, " polymorphous perversity, " this pure desire for pleasure.

弗洛伊德有一个美妙的词组，“多态的反常”，这种对快乐的纯粹渴望。

But, as the name " polymorphous" suggests, it can be a bit of everything, from itchy, fluid-filled blisters to simple raised bumps or red patches.

但是，正如“多形性” 这个名字所暗示的那样，它可以是任何东西， 从发痒、充满液体的水泡到简单的凸起的肿块或红色斑块。

But there’s a similar condition that affects as many as 10 to 20 percent of some human populations called polymorphous light eruption, or PMLE. It’s also a sun-triggered rash.

但是有一种类似的情况会影响多达 10% 到 20% 的某些人群，称为多形性日光性喷发 (PMLE)。这也是一种阳光引发的皮疹。
