Polymorphous light eruption (PMLE) is the most common photodermatosis characterized by pruritic papules and papulovesicles, which appear hours to days following ultraviolet (UV) exposure. Herein, the authors report successful treatment of generalized plaque psoriasis with Goeckerman regimen in a patient despite new onset iatrogenic PMLE following narrowband (NB) UVB therapy. Although further studies are necessary, this case suggests that the co-existence of psoriasis and PMLE should not prevent the use of phototherapy; phototherapy, especially as part of the Goeckerman regimen, remains a valuable treatment option for psoriasis in patients with PMLE.
