What is the most common form of impetigo?

Nonbullous impetigo is the most prevalent type of impetigo seen in children. This form typically starts as small vesicles that quickly rupture and form honey-colored crusted lesions, primarily affecting the face, particularly around the nose and mouth, as well as the extremities. It is often caused by Staphylococcus aureus or Streptococcus pyogenes, making it highly contagious and easily spread through direct contact.

The clinical significance of nonbullous impetigo lies in its characteristic appearance and rapid progression, which requires prompt recognition and treatment to prevent further spread and complications. The lesions in nonbullous impetigo can resolve with appropriate topical antibiotics, and the disorder is generally self-limiting when treated properly.

In comparison, bullous impetigo usually presents with larger, fluid-filled blisters and is less common in the pediatric population. Ecthyma, on the other hand, is a deeper infection that results in erosions after the vesicles rupture and can lead to scarring, making it less typical than the more superficial nonbullous impetigo. While a staph infection can denote various skin or systemic infections caused by Staphylococcus, it is not specific enough to define as a form of impet
