Psoriasiform Dermatitis - the Derms on Drugs take on your worst nightmare when it comes to path reports. Dermatitis? Psoriasis? Both? Neither? We'll get into the weeds with Amber Atwater, who looked at what the final diagnoses ended up being in hundreds of patients with psoriasiform dermatitis that gives us some clues on how to approach these patients. We also review the latest work on idiopathic erythroderma - not so idiopathic anymore, thanks to the hard work and genius of Shawn Kwatra at the University of Maryland. And, stick around to the end for some hard hitting trivia on the American Contact Dermatitis Society's last 25 years of Allergens of the Year.

Join us for another episode of Derms on Drugs, brought to you by Scholars in Medicine.
