A 13-year-old boy presents for evaluation of asymptomatic papuleson his penis for the past month. The number of lesions has increased slowly. He reports no other associated systemic symptoms and neither a preceding sexual exposure nor a history of sexually transmitted disease. A viral infection was suspected in medical clinics, but no improvement was observed after treatments. Clinical examination reveals many tiny, smooth, translucent, and shiny skin-colored papules affecting nearly all the glans penis and prepuce (Figure). A few similar lesions are distributed on the thighs.
