A 17-year-old boy developed linear brown spots on his abdomen and chest while on a beach vacation with his family the week prior. The patient first noticed the lesions a few days after making a freshly squeezed limeade and spent the day at the beach. On examination, he has hyperpigmented macules of varying sizes located on the torso. Upon closer inspection, the lesions appear to have bizarre shapes consistent with streaks and drips. The lesions are asymptomatic (Figure).
