Final answer:
Vesicular and bullous lesions typically evolve into erosions when they rupture, especially in skin conditions like impetigo where encrusted sores form after the lesions open.
Step-by-step explanation:
Vesicular and bullous lesions typically evolve into erosions in dermatological response to damage lesions. These types of lesions, often presented in conditions such as impetigo, begin as fluid-filled structures on the skin. Depending on whether the impetigo is nonbullous or bullous, these vesicles, pustules, or bullae can rupture resulting in the formation of encrusted sores, which are examples of erosions. In the context of bullous impetigo, after the bullae have ruptured, the result is typically larger draining, crusted lesions that are erosive in nature.
