    "goal": "Determine the most likely diagnosis based on the provided clinical presentation and lab findings."

  "summary": "In this clinical scenario, we are tasked with diagnosing a 1-year-old patient who exhibits hypertrophic scarring, erythema, and spasticity, with negative anti-Mi-2 antibodies. The symptoms suggest a condition related to skin and muscle involvement. Among the options provided, dermatomyositis is characterized by similar symptoms, including skin changes and muscle weakness, making it the most likely diagnosis despite the negative lab result for anti-Mi-2, which is not definitive for all cases of dermatomyositis."
