A 10-year-old presents with flesh-colored dome-shaped papules with central umbilication distributed over the trunk and extremities. Lesions have been present for 3 months and are asymptomatic. The diagnosis and CORRECT management approach is:

  • A Verruca vulgaris — cryotherapy is mandatory
  • B Molluscum contagiosum — usually self-limiting; curettage or cantharidin for symptomatic cases
  • C Milia — no treatment required and will resolve spontaneously in weeks
  • D Keratosis pilaris — topical keratolytics for cosmetic concern
Correct answer: B. Molluscum contagiosum — usually self-limiting; curettage or cantharidin for symptomatic cases

Explanation

Molluscum contagiosum (poxvirus) presents with multiple pearly, flesh-colored dome-shaped papules with central umbilication, typically 2–5 mm, distributed over trunk and extremities. It is highly contagious. In immunocompetent children, lesions are self-limiting (resolving in 6–18 months). Treatment is offered for cosmetic concern or extensive spread: curettage, cantharidin, or tretinoin. Verruca vulgaris (warts) have rough, hyperkeratotic surfaces without umbilication. Milia are tiny white epidermal inclusion cysts in neonates. Keratosis pilaris causes follicular papules on upper arms/thighs without umbilication.
