What type of lesions are primarily seen in impetigo?

  1. Papules

  2. Pustules and vesicles

  3. Ulcers

  4. Rosacea

The correct answer is: Pustules and vesicles

Impetigo is primarily characterized by pustules and vesicles. This condition, usually affecting children, presents with fluid-filled blisters that can rupture, leading to the formation of honey-colored crusts. Pustules are small, pus-filled lesions, while vesicles are similar but contain clear fluid. These types of lesions are essential in diagnosing impetigo, as they are indicative of the bacterial infection typically caused by Staphylococcus aureus or Streptococcus pyogenes. The other types of lesions mentioned do not align with the typical presentation of impetigo. While papules are small raised bumps that can occur in various skin conditions, they are not specifically indicative of impetigo. Ulcers represent deeper skin loss and are not a primary feature of this condition, and rosacea, characterized by redness and visible blood vessels primarily on the face, is a completely different dermatological disorder and does not involve the lesions associated with impetigo. Thus, the presence of pustules and vesicles is the defining feature of impetigo, making this the correct identification for the lesions primarily seen in the condition.
