Tietze syndrome is a benign inflammation of one or more of the costal cartilages. It was first described in 1921 by the German surgeon Alexander Tietze (1864–1927). Though thought to be the same conditions, Tietze syndrome is not the same as costochondritis. Tietze syndrome is differentiated from costochondritis by swelling of the costal cartilages, which does not appear in costochondritis. Like costochondritis, it was at one time thought to be associated with, or caused by, a viral infection acquired during surgery. This is now known not to be the case, as most sufferers have not had recent surgery. ==Signs and symptoms== The main presentation of the syndrome is significant, acute pain in the chest, along with tenderness and some swelling of the cartilages affected, which is commonly palpable on examination. Perceived pain is often exacerbated with respiration. Although many times it can be extremely painful, to the point of being debilitating, Tietze's Syndrome is considered to be a benign condition that generally resolves in 12 weeks. However, it can often be a chronic condition. The associated chest pain may present similarly to angina pectoris, normally associated with heart disease, and can cause hyperventilation, anxiety or panic attacks, syncope (passing out), and temporary hypoesthesia (numbness) or paralysis. Many cases of myocardial infarction (heart attack) patients have been re-considered and improperly diagnosed, due to the identical nature of the symptoms. In females, it is often misdiagnosed as mastalgia. Costochondritis symptoms are similar to Tietze's, the prime difference being that the pain radiates to the arms and shoulders in the latter. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tietze syndrome」の詳細全文を読む スポンサード リンク
