4. Erythematous papules, papulovesicles, and plaques appeared on sun-exposed surfaces of the skin.
Diagnosis: Polymorphous light eruption (PMLE) manifesting as erythematous papules over the cheek and dorsal aspect of the nose. Similarities between PMLE and rosacea include exacerbation by sun exposure and a higher prevalence in fair-skinned individuals.4 Also, in both conditions erythematous papules appear on the face and may be pruritic and in some instances painful; however, unlike rosacea, which is chronic, PMLE tends to be intermittent and recurrent, typically occurring in the spring and early summer months.
