A case report is a detailed description of a single clinical case or a small group of cases. It typically includes information about the patient's medical history, symptoms, diagnostic tests, treatment, and outcomes. Case reports are often used to document rare or unusual medical conditions, unexpected complications of treatment, or novel therapeutic approaches. They can provide valuable insights into clinical practice, contribute to medical knowledge, and inform future research and treatment strategies. Case reports are typically published in medical journals to share important clinical findings with the medical community.
