Impetigo is a highly contagious skin infection characterized by the appearance of isolated pustules that eventually develop a honey-colored crust, particularly around the mouth and face. This condition is primarily caused by bacterial infections, usually from Staphylococcus aureus or Streptococcus pyogenes, making it common in young children but can affect individuals of any age. The presence of the honey-colored crust differentiates impetigo from other skin conditions. While psoriasis is a chronic autoimmune condition leading to thick, scaly patches, eczema (atopic dermatitis) manifests as itchy, inflamed skin usually without such crusting. Dermatitis is a broad term encompassing various inflammatory skin conditions but lacks the specific pustular and crusting feature that defines impetigo. Therefore, recognizing impetigo's distinctive clinical presentation is crucial for accurate diagnosis and appropriate treatment.
