What is the appearance of lesions associated with impetigo?

Lesions associated with impetigo typically present as creamy yellow and crusty. Impetigo is a highly contagious skin infection caused mainly by Staphylococcus aureus or Streptococcus pyogenes. The initial lesions often start as small red bumps or blisters that can rapidly develop into pustules filled with fluid. When these pustules rupture, they leave behind a honey-colored crust that is thick and crusty in texture, which is characteristic of this condition.

This appearance is essential for differential diagnosis, as it allows healthcare providers to distinguish impetigo from other skin conditions that may present with similar symptoms but have different characteristics. The creamy yellow crust is a significant indicator of infection, helping clinicians identify and treat the condition appropriately. Other types of lesions, such as flat and brown, or red and scaly, do not fit the typical presentation of impetigo and may suggest other dermatological conditions. Bumpy and painful lesions can also be associated with other skin issues but do not accurately describe the classic appearance of impetigo.
