title: Notalgia paresthetica: treatment using intradermal botulinum toxin A.
abstract: BACKGROUND
  Notalgia paresthetica is a sensory mononeuropathy that affects dorsal segments T2 to T6. It can have a significant effect on quality of life. Numerous treatments have been used with variable results.
  
  
  METHODS
  Five patients diagnosed with notalgia paresthetica were treated with intradermal botulinum toxin A. None had achieved relief of the pruritus with previous treatments.
  
  
  RESULTS
  Variable results were observed after the administration of intradermal botulinum toxin. Complete resolution of the pruritus was not achieved in any of the patients.
  
  
  CONCLUSIONS
  Botulinum toxin A appears to be a safe therapeutic option for patients with notalgia paresthetica. However, data currently available come from small patient series, making it difficult to draw definitive conclusions regarding the true efficacy and long-term effects of this treatment.
