Impetigo is a highly contagious skin infection often seen in children, characterized by the evolution of lesions throughout its course. As the condition progresses, lesions initially appear as small, red sores that quickly develop into vesicles, which then become pustules. Eventually, these pustules rupture, leading to the formation of crusty scabs that are typically golden-yellow in color.

The development of crusty scabs is a hallmark of impetigo and signifies that the infection is progressing and healing. This progression reflects the body's natural response to the infection, as it attempts to seal the area and prevent further microbial invasion. The presence of these crusty scabs differentiates impetigo from other skin conditions, making it an important feature for diagnosis.

In contrast, flat pink spots, red raised bumps, and pustules represent earlier phases or different skin conditions altogether, and do not accurately depict the final and recognizable appearance of lesions in active impetigo. Understanding the typical progression of impetigo can help practitioners identify and treat this common skin condition effectively.
