Early lesions of staphylococcal impetigo appear as thin, flaccid blisters that may demonstrate cloudy contents or layering of pus (Fig. 27-1). The base of the blister may demonstrate variable erythema. Histologically, the blisters are very superficial; the split occurs beneath the stratum corneum. For this reason, the blisters quickly collapse and may demonstrate a shiny lacquered appearance. Older lesions demonstrate a yellowish crust.
