Contact Dermatitis: Clinical Pearls


Matthew J. Zirwas, MD

What do you need to know about contact dermatitis?

  • Add 10 allergens to the TRUE Test to dramatically improve diagnostic accuracy
  • Lip dermatitis is much more likely to be contact dermatitis if it extends beyond the vermillion border
  • Shampoo and conditioner are a very common cause of eyelid dermatitis
  • You can prepare allergens for patch testing 24 hours ahead of time, except two types: fragrance and acrylates
  • You can patch test patients on prednisone
  • Giving too much information about allergens is as bad as not giving enough
  • Use videos to make patient education easier, faster, and more effective
