His mother says that he has no history of dermatological problems. He was born at term and has been healthy except for recurrent episodes of otitis media. His immunizations are up-to-date. He appears pale. His temperature is 37C 98.6F, pulse is 110min, respirations are 26min, and blood pressure is 10262 mm Hg. Examination shows vesicles and flaccid bullae with thin brown crusts on the chest. Lateral traction of the surrounding skin leads to sloughing. Examination of the oral mucosa shows no abnormalities. Complete blood count is within the reference range. Which of the following is the most likely diagnosis?? A: Bullous impetigo, B: Dermatitis herpetiformis, C: Stevens-Johnson syndrome, D: Bullous pemphigoid, E: Pemphigus vulgaris,  <response>: Based on the information provided in the question stem, this appears to be a case of bullous impetigo in a young child. The key findings are:- 3-year-old boy - Pruritic rash on chest for 3 days- No prior history of skin conditions- Otherwise healthy except for otitis media- Pale appearance, fever, tachycardia - Vesicles and flaccid bullae with thin brown crusts on chest- Sloughing of skin with lateral traction- Normal oral mucosa- Normal CBCThis presentation is most consistent with bullous impetigo, a superficial skin infection caused by Staphylococcus aureus or Streptococcus pyogenes. The vesicles, bullae, and sloughing skin are characteristic. The lack of mucosal involvement and systemic symptoms differentiates this from Stevens-Johnson syndrome. The other options can be ruled out based on the acute presentation in a previously healthy child.A: Bullous impetigo
