11.21 Impetigo


Presentation

  • Parents will usually bring their children in because they are developing unsightly skin lesions, which may be pruritic and are found most often on the face or other exposed areas. Streptococcal lesions consist of irregular or somewhat circular, red, oozing erosions, often covered with a yellow- brown crust. These may be surrounded by smaller erythematous macular or vesiculopustular areas. Staphylococcal lesions present as bullae which are quickly replaced by a thin shiny crust over an erythematous base.

    Discussion

    Impetigo is usually self-limiting and it is believed that antibiotic treatment does not alter the subsequent incidence of secondary glomerulonephritis. Impetigo is very contagious among infants and young children and may be associated with poor hygiene or predisposing skin eruptions such as chicken pox, scabies, and atopic and contact dermatitis.
