The rash started around the mouth before spreading to the trunk and extremities. Her temperature is 38.6C 101.5F. Examination shows a diffuse erythematous rash with flaccid bullae on the neck, flexural creases, and buttocks. Gentle pressure across the trunk with a gloved finger creates a blister. Oropharyngeal examination shows no abnormalities. Which of the following is the most likely underlying mechanism of these skin findings?? A: Toxin-induced cleavage of desmoglein, B: Bacterial production of erythrogenic toxin, C: Bacterial invasion of the epidermis, D: Autoantibody deposition in stratum spinosum, E: Autoantibody binding of hemidesmosomes,  <response>: This is a clinical vignette describing a 3-month-old infant with fever, irritability, rash, and blisters. The key findings are a diffuse erythematous rash that started around the mouth before spreading, flaccid bullae in flexural areas and with gentle pressure, and no abnormalities on oropharyngeal exam. This presentation is most consistent with staphylococcal scalded skin syndrome SSS, which is caused by exfoliative toxins produced by Staphylococcus aureus. The underlying mechanism is toxin-mediated cleavage of desmoglein-1 in the stratum granulosum, leading to intraepidermal blistering.A: Toxin-induced cleavage of desmoglein
