This morning the patient was irritable and had a fever which gradually worsened throughout the day. He also developed a rash prior to presentation. He was previously healthy and is not currently taking any medications. His temperature is 102.0F 38.9C, blood pressure is 9050 mmHg, pulse is 160min, respirations are 17min, and oxygen saturation is 98 on room air. Physical exam is notable for a scarlatiniform rash with flaccid blisters that rupture easily, covering more than 60 of the patients body surface. The lesions surround the mouth but do not affect the mucosa, and palpation of the rash is painful. Which of the following is the most likely diagnosis?? A: Staphylococcal scalded skin syndrome, B: Stevens Johnson syndrome, C: Toxic epidermal necrolysis, D: Toxic shock syndrome, E: Urticaria,  <response>: Based on the description of a 3-year-old boy with high fever, irritability, and a scarlatiniform rash covering a large body surface area, the most likely diagnosis is staphylococcal scalded skin syndrome SSS. SSS typically affects children under age 5 and presents with a fever, irritability, and a diffuse erythematous rash that resembles a burn. The rash starts around the mouth but spares the mucous membranes. Nikolsky sign, where light pressure leads to sloughing of the outer layer of skin, is typically positive. Stevens Johnson syndrome and toxic epidermal necrolysis present with more severe mucocutaneous involvement. Toxic shock syndrome may present similarly but would be less likely in a previously healthy child. Urticaria presents with hives rather than a scarlatiniform rash.A: Staphylococcal scalded skin syndrome
