A 27-year-old male presents with irregular skin discoloration on his upper back after returning from a 2-week vacation in Ibiza. Although he applied sunscreen intermittently, he did experience mild sunburn in the area, which has since healed. He doesn’t experience any pain or itching, but he is self-conscious about the appearance of his skin. During the examination, there are scattered pale pink macules covered with fine scales visible over his upper back, despite having a suntan. What is the most probable diagnosis?
