Which infection presents as dome-shaped papules with central dimples in children?

• A. Impetigo
• B. Varicella
• C. Ringworm
• D. Molluscum contagiosum

Answer: (D)

The distinguishing feature here is the appearance of the skin lesions. Molluscum contagiosum causes firm, dome-shaped, flesh-colored papules that often have a small central dimple or umbilication. This central indentation is a classic hallmark and helps set it apart from other common childhood rashes.

Impetigo, by contrast, presents with pustules and vesicles that rupture to form honey-colored crusts, not dome-shaped papules with central dimpling. Varicella (chickenpox) features vesicular lesions in crops at different stages, described as dew drops on a rose petal, and they aren’t characteristically umbilicated. Ringworm (tinea corporis) shows annular, scaly patches with central clearing, rather than dome-shaped papules with a central dimple.

Thus, the presentation of dome-shaped papules with a central dimple in a child aligns best with Molluscum contagiosum.
