Forearm Neuropathy and Pruritus

Abstract

Five adult patients (four of them men) had episodic brachioradial pruritus associated with forearm paresthesia and hypalgesia. No cervical, shoulder, or forearm trauma was known. Onset was variable, but two had had the condition for more than ten years. In each, sensory alteration was detectable by pinprick and temperature in the distribution of the posterior cutaneous nerve of the forearm supplying the skin over the proximal portion of the brachioradial muscle. This seems to be a benign neuropathy.
