A young man in his 20s with no significant medical history presented with an annular eruption on the face and upper torso of 2 weeks’ duration. The eruption began on his upper back, at which time he felt well. He then received significant sun exposure while on a 7-day trip to Miami, Florida. After returning from his trip, he noted that the eruption had become more prominent on his back and had spread to his face. In addition, he began to have a febrile illness with joint pain and swollen nodes, which subsequently resolved without treatment. The lesions continued to rapidly enlarge without scaling, and his plaques were not associated with itching or pain. The patient was not taking any medications at the time and denied any recent international travel.
