Impetigo
Rounded, crusted papules and plaques on face. Crust is yellow and heavy-appearing. Lesions have some vesiculation at outermost edge.
Primary lesion is a flaccid, thin-roofed bulla. The larger lesions are secondary; they are erosions with peripheral collarette of scale, which is a typical evolution of bullous impetigo.
Faint erythema and yellow, honey-colored crusting of the nare base. Nasal carriers of S. aureus do not typically show this change; the carrier state is identified by inner nasal mucosa culture.
