He was diagnosed with acquired immunodeficiency syndrome AIDS 2 months ago which prompted the initiation of prophylactic antibiotics. The vital signs include: blood pressure 11272 mm Hg, temperature 40.0C 104.0F, respiratory rate 22min, and heart rate 95min. He has 20 total body surface area TBSA skin slough with scattered vesicles and erosions throughout his face and extremities, as shown in the image. He does have erosions on his lips, but he does not have any other mucosal involvement. Which of the following is most consistent with this patients findings?? A: Erythema multiforme, B: Staphylococcal scalded skin syndrome, C: Stevens-Johnson syndrome, D: Drug rash with eosinophilia and systemic symptoms, E: Toxic shock syndrome,  <response>: This is a clinical vignette describing a patient with AIDS who developed a skin rash after being started on trimethoprimsulfamethoxazole. The rash is described as involving 20 TBSA with vesicles and erosions on the face and extremities. The patient also has a fever and tachycardia. The key features here are the development of a severe rash with mucocutaneous involvement shortly after starting a new medication in an immunocompromised patient. This makes Stevens-Johnson syndrome the most likely diagnosis. Erythema multiforme is a hypersensitivity reaction that can look similar but usually follows certain infections or medications and is self-limited. Staphylococcal scalded skin syndrome involves blistering but no mucous membrane involvement. Drug rash with eosinophilia is less likely with the lack of blood work showing eosinophilia. Toxic shock also causes rash but has more systemic toxicity.C: Stevens-Johnson syndrome
