question: Q:A 13-year-old boy re-presents to his pediatrician with a new onset rash that began a few days after his initial visit. He initially presented with complaints of sore throat but was found to have a negative strep test. His mother demanded that he be placed on antibiotics, but this was refused by his pediatrician. The boy's father, a neurologist, therefore, started him on penicillin. Shortly after starting the drug, the boy developed a fever and a rash. The patient is admitted and his symptoms worsen. His skin begins to slough off, and the rash covers over 30% of his body. His oropharynx and corneal membranes are also affected. You examine him at the bedside and note a positive Nikolsky's sign. What is the most likely diagnosis?? 
  {'A': 'Erythema Multiforme', 'B': 'Stevens-Johnson Syndrome', 'C': 'Toxic Epidermal Necrolysis', 'D': 'Rocky Mounted Spotted Fever', 'E': 'Pemphigus Vulgaris'},
