I stumbled upon this website that teaches the different types of primary/secondary lesions, as well as the terms used to describe their patterns/distributions. There are many terms used to describe different types of lesions and this is a great resource to understanding the meaning of each of them! Not only does it give the definition of a term, it also provides images so you can see examples. There is even a short quiz after you’ve gone through the material. This will be posted on the resources page for future reference to anyone who may find it of use. I definitely recommend taking advantage of this!
