Acropachy or thyroid acropachy refers to a dermopathy associated with Graves' disease. It is characterized by soft-tissue swelling of the hands and clubbing of the fingers. Radiographic imaging of affected extremities typically demonstrates periostitis, most commonly the metacarpal bones. The exact cause is unknown, but it is thought to be caused by stimulating auto-antibodies that are implicated in the pathophysiology of Graves thyrotoxicosis. There is no effective treatment for acropachy. Since it is closely associated with Graves disease, it is associated with other manifestations of Graves disease, such as Graves ophthalmopathy and thyroid dermopathy. Hereditary acropachy (also known as "isolated congenital nail clubbing") may be associated with HPGD. ==See also== * Periosteal reaction * (Radiopaedia.org: Thyroid acropachy ) 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「acropachy」の詳細全文を読む スポンサード リンク
