A 21-Day-Old Boy with an Annular Eruption

A 21-day-old healthy black male presented with erythematous annular, scaly plaques with pustules on his upper cheeks, forehead, and anterior scalp. Despite the application of a topical corticosteroid cream, there was no improvement. Physical examination showed the patient was alert and active, with no alopecia or palpable lymph nodes. Potassium hydroxide skin preparation was negative for fungal elements, and a fungal culture and serum laboratory tests were conducted. The case highlights the need for thorough evaluation in neonatal dermatological conditions.
