Brachioradial pruritus.

Fourteen patients with brachioradial pruritus are described. In six patients the right arm was involved, in three the left arm, and in five both arms. In four of five patients so examined there was roentgenographic evidence of cervical vertebral osteoarthritis. Although sun exposure may be of etiologic importance, some, or perhaps most, cases may be due to nerve injury, either secondary to lesions of the cervical spine or perhaps resulting from nerve compression by other structures.
