Rash, Rashes, and the Art of Skin Diagnosis | Part 1

Self-paced online dermatology course
The word “rash” or “skin rash” is used quite frequently to describe a variety of skin conditions. 

Rash is a generic term however and most people use the word rash to mean an eruption of skin lesions that covers areas of skin. In contrast, a single small lesion, like a pimple, mole, tumor, or growth, is not usually called a rash. 

Properly diagnosing and treating a skin condition requires a more detailed understanding of the true cause of the condition. 

In most situations simply using the term “skin rash” is not adequate.


The field of dermatology has a well-established terminology for describing skin lesions. These descriptive terms facilitate the diagnostic process because many diseases have distinctive features that fall into recognizable categories.

This course is designed to:

Introduce students of all backgrounds to the key terms and clinical concepts of dermatology.
Provide an introduction to the top list of dermatology conditions with which all students and clinicians should be 
familiar.
Increase exposure to building a robust differential based on 
the specific findings of a patient.
The final sections of this course are design to work as a companion with VisualDx -- the leading dermatologic decision support system.  If you or your institution has access to VisualDx, simply log in to take advantage of this interactive content.  A free trial is also available for those who are new to the system.
