impetigo bullosa

bullous impetigo impetigo caused by infection with Staphylococcus aureus, seen most often in newborns but sometimes in older children or adults. Skin eruptions begin as small vesicles that enlarge to form flaccid bullae, sometimes up to 5 cm in diameter, with erythematous rims; the lesions later rupture and form a thin, varnishlike crust. Called also i. contagiosa bullosa and i. neonatorum.
