Brachioradial Pruritus

Excerpt

Brachioradial pruritus (BRP) is a localized neuropathic dysesthesia of the dorsolateral upper extremities. It is commonly seen in middle-aged white females with a seasonal predilection for warmer summer months. Cervical radiculopathy or neuropathy in the upper extremities in conjunction with ultraviolet radiation (UVR) are thought to be causative. Despite the wide variety of etiologies for pruritus, identification of brachioradial pruritus by dermatologists through the history and physical exam has been straightforward. Further workup, such as imaging, labs, and referral to specialists is rarely required. Therapeutic options are numerous and well-tolerated. Because of the benign transient nature of brachioradial pruritus, the number of reported cases and current studies are relatively low.
