Differential Diagnosis of an Unusual Rash | Part 4

If you can accurately describe a rash and have taken a basic patient history, you are very close to a diagnosis. While the “common lists” can serve as a foundational dermatology curriculum for medical student education and help with common disease diagnosis, arriving at a diagnosis when a patient presents with an unusual rash and a complex medical history can be challenging.

Case Study
