Snapshot A 12-year-old boy with no significant past medical history presents with acne to his pediatrician’s office. He has recently started practice for the wrestling team. He admits to not maintaining great hygiene, eating lots of junk food, and being stressed about an upcoming meet. On physical exam, he has dozens of erythematous papules, pustules, and cysts. On closer exam, he also has atrophic scars on the lateral forehead, consistent with permanent scarring from previous acne lesions. He is started on topical retinoids and topical benzoyl peroxide. His pediatrician suggests that he also consider a systemic retinoid if this topical therapy does not work.
