(For my dermatopathology library, go here: https://kikoxp.com/posts/5084)
All of my online bone & soft tissue pathology content organized by topic in one place! Just use Ctrl+F, Command+F, or Find in Page to search this page for the entity/topic you need info about to see what I have available. I’ve saved text from many pathology reports I have written over the years; I will be editing and releasing those over time here on this page. As I release new videos, pics, and digital slides online, I’ll add links to them here. My goal is for this to eventually become a free online unofficial bone/soft tissue pathology fellowship-level course for those who need extra education in this area. Please bookmark this page and check back regularly, as I will be continually adding content.
Best wishes,
Jerad M. Gardner, MD
