Pruritic rash in vulvovaginal area of 2-year-old girlMay 12th 2023
Three months ago, a healthy 2-year-old girl presented with a mildly pruritic rash with erythematous plaques, some silvery white, in the vulvovaginal area. She had no vaginal discharge or other symptoms. The rash is now more widespread, and new lesions have recently appeared on her lower back and thighs. What's the diagnosis?
