A patient presenting painful chest wall swelling: Tietze syndrome / 世界急诊医学杂志（英文）

@#Patients frequently visit the emergency room with acute chest pain. While some potentially life-threatening disorders may cause the pain, in approximately 80% of cases, the chest pain source is benign, and musculoskeletal chest pain accounts for nearly 20%– 50% of those cases.[1–6] Thus, pain caused by benign and pathological conditions of the chest wall encountered in the emergency department is sometimes incorrectly attributed to angina pectoris or pleuritic and other serious cardiopulmonary diseases.
