What you need to know • PMLE is the most common photodermatosis that you will see in your office. And you probably won’t ever see the rash. It is a diagnosis of exclusion.

What you need to know • If its photoallergic contact dermatitis it will be due to sunscreens almost always. If you can photopatch test to confirm the diagnosis (and you should) but if you can’t then use physical blockers (titanium and zinc) only. Remember however that sunscreens are used in many non-sunscreen agents like shampoos and remember that there can be short term persistent light reactivity.
