What is a characteristic feature of impetigo?

• A. Red spots that itch
• B. Yellow/brown crust with blisters
• C. Dry skin with scale formation
• D. Fluid-filled blisters with no pain

Answer: (B)

The characteristic feature of impetigo is the presence of a yellow or brown crust that typically forms over blisters. This condition is a bacterial skin infection, often caused by Staphylococcus aureus or Streptococcus pyogenes, and is commonly seen in children. Initially, impetigo may appear as red sores or blisters, which quickly burst, ooze fluid, and then develop the distinctive crust. The yellow or brown crust is a hallmark because it results from the drying and healing process of the lesions. This crusting can often be found around the nose and mouth, but it can affect any part of the body. Understanding this feature is crucial for identifying and treating impetigo effectively, as early intervention can help prevent the spread of the infection and promote quicker healing.
