Write answer in between .Q:An 8-year-old girl is brought to the emergency department because of a 2-day history of low-grade fever, itchy rash, and generalized joint pain. The rash initially started in the antecubital and popliteal fossae and then spread to her trunk and distal extremities. One week ago, she was diagnosed with acute sinusitis and was started on amoxicillin. She has no history of adverse drug reactions and immunizations are up-to-date. Her temperature is 37.5C 99.5F, pulse is 90min, and blood pressure is 11070 mm Hg. Physical examination shows periorbital edema and multiple erythematous, annular plaques of variable sizes over her entire body. One of the lesions in the right popliteal fossa has an area of central clearing and the patients mother reports that it has been present for over 24 hours. Urinalysis is normal. Which of the following is the most likely diagnosis?? A: Serum sickness-like reaction, B: Stevens-Johnson syndrome, C: Pemphigus vulgaris, D: Drug reaction with eosinophilia and systemic symptoms, E: IgA vasculitis,  <response>: This is a clinical case scenario involving an 8-year-old girl who recently started taking amoxicillin for acute sinusitis and now presents with fever, rash, and joint pain. The description of the rash as being annular plaques that started in the antecubital and popliteal fossae and spread to the trunk and extremities along with the history of recent amoxicillin use makes this most consistent with a drug reaction. The options include various types of drug reactions and vasculitides. Serum sickness-like reaction is the most likely diagnosis given the typical morphology and distribution of the rash along with the recent antibiotic exposure. Stevens-Johnson syndrome and drug reaction with eosinophilia and systemic symptoms DRESS are less likely given the lack of mucosal involvement or organ dysfunction. Pemphigus vulgaris and IgA vasculitis would not be expected to occur in this temporal pattern with antibiotic exposure.A: Serum sickness-like reaction
