| 要約: | Rheumatic disorders and infections often share overlapping clinical and immunopathological features, posing significant diagnostic challenges, especially in pediatric populations, where infections are more common and autoimmune presentations may be atypical. Autoimmune and autoinflammatory disorders may initially mimic infections, while certain infections can present with rheumatologic manifestations. Misdiagnosis in these cases can result in delays in appropriate treatment or lead to unnecessary interventions. This case-based review highlights selected pediatric rheumatic disorders frequently mistaken for infections, with a focus on distinguishing clinical features and key diagnostic considerations to aid accurate and timely diagnosis.
