Answer

Also consider the following:

  • Neurotic excoriations: Patients with brachioradial pruritus can excoriate the affected area, while the typical neurotic excoriation patient also has lesions on other accessible areas. An interface and a common etiology may exist between these 2 disorders.

  • Notalgia paresthetica: This condition is typically associated with pruritus, pain, paresthesia, and hyperesthesia on the back. [31] Often, a well-circumscribed hyperpigmented patch is present in the symptomatic area.

  • Zoster sine herpete: This is an unusual manifestation of herpes zoster in which no cutaneous rash is observed. Unilateral paresthesias may be pronounced.

  • Atopic dermatitis: Itch may be severe, although it usually involves flexor aspects of the elbows and is not associated with tingling. The Medscape Atopic Dermatitis Resource Center may be of interest.
