I think the key is that they don't mention any blistering. From UTD: A diagnosis of polymorphous light eruption (PMLE) is usually based upon the clinical finding of a pruritic eruption of papules or plaques on exposed skin (picture 1A-C) and the patient's history of a similar eruption occurring in spring or early summer after sun exposure and gradually improving over the summer months. It is important to exclude other photosensitive skin conditions (table 1). (See 'Differential diagnosis' below.)

1) Superficial (first-degree) = Epidermis ~ presents as red skin without blisters
2) Superficial partial thickness (second-degree) = Extends into superficial (papillary) dermis ~ Presents with redness with clear blister & blanches with pressure
3) Deep partial thickness (second-degree) = Extends into deep (reticular) dermis ~ presents as yellow or white skin with less blanching. May be blistering.
4) Full thickness (third-degree) = Extends through entire dermis ~ presents as stiff and white/brown skin. No blanching.
5) Fourth-degree = Extends through entire skin, and into underlying fat, muscle and bone ~ presents as black skin; charred with eschar
