title: Treatment of a patient with multiple cutaneous piloleiomyoma-related pain with a local injection of triamcinolone acetonide.
abstract: BACKGROUND
  Multiple cutaneous piloleiomyomas are rare, frequently painful and difficult-to-treat benign tumours originating in the arrectores pilorum muscles of the hair follicles.
  
  
  OBJECTIVE
  The aim of this study was to determine the efficacy of a local injection of triamcinolone acetonide in relieving cutaneous piloleiomyoma-related pain.
  
  
  METHODS
  A patient with multiple painful piloleiomyomas was treated with weekly local injections of triamcinolone acetonide into the nodules and papules for 3 weeks.
  
  
  RESULTS
  The patient's nodules and papules became smaller, and the pain disappeared. At 1-year follow-up, there were no side effects, pain recurrence or significant enlargement of any of the injected lesions.
  
  
  CONCLUSIONS
  Our study demonstrates that local injection of triamcinolone acetonide may be a promising new treatment option for multiple painful cutaneous piloleiomyomas.
