Manage episode 289358818 series 1397179
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 (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
