cbreland I agree with this explanation. Thought that they would make us decide between S aureus and GAS (bullous v. non-bullous impetigo) but seems like they went easy on us +1

jer040512 It sounded more like Scalded Skin Syndrome to me. I saw this in Amboss and thought i'd post it here. "SSSS belongs to the spectrum of diseases mediated by specific staphylococcal toxins, which also includes bullous impetigo, toxic shock syndrome (TSS), and Staphylococcus aureus food poisoning. Unlike TSS, SSSS does not have systemic manifestations (e.g., liver, kidney, bone marrow, and CNS involvement)!" +9

plaguedbyspleen Staphylococcal scalded skin syndrome differs from bullous impetigo. Both are blistering skin diseases caused by staphylococcal exfoliative toxin. However, in bullous impetigo, the exfoliative toxins are restricted to the area of infection, and bacteria can be cultured from the blister contents. In staphylococcal scalded skin syndrome the exfoliative toxins are spread hematogenously from a localized source causing widespread epidermal damage at distant sites. +1
