Podcast 656: Rashes

Contributor: Peter Bakes, MD

Educational Pearls:

  • Lyme disease gives a single expanding target lesion with central clearing called erythema chronicum migrans
  • Erythema multiforme is another targetoid rash that presents with multiple target lesions
  • Characterized into erythema minor and major based on severity but typically resolves
  • More severe hypersensitivity reactions include Stevens-Johnson Syndrome (<10% skin involvement), or Toxic Epidermal Necrolysis (>30% skin involvement)
  • SJS and TEN is associated with NSAIDS including aspirin, antiemetics like phenergan, anticonvulsants like dilantin or phenobarbital, and antibiotics like penicillin or sulfa drugs
  • Other causes include viral illnesses like Herpes simplex virus or mycoplasma pneumoniae
  • Treat by removing offending agent and treat supportively with monitoring for rash progression to SJS or TEN
