38 classic dermpath cases in 1.25 hours. Rapid fire board review style virtual slide session for my dermatology residents. I recorded so I could share it with all of you, too. Enjoy!
Virtual slides courtesy of my friend and colleague, the amazing Dr. Tammie Ferringer (the platform they are hosted on doesn't have the ability for public sharing of the WSI files...sorry!)

All I can do is salute you king of pathology pedagogy! ...and subscribe, and put a like on every video, and on every positive comment of every video. Immeasurable gratitude from Sweden!
You made my day. Thank you!
Thank you foe explaining the difference between a keratin whorl and a keratin pearl, especially in regards to the malignant location of the pearls.
You sir are a legend.Your videos have saved my life and those of my colleagues over here in England.
So glad to be of service! My best wishes to you and your colleagues in England!
This was really awesome.
Many thanks.
Excellent thanks
I learnt a whole lot of things today.. thanks
Warry dyskeratoma looked like SCAP to me.. a bit confused
do you have a general approach to these types of lesions? i.e. how do you generate a differential?
...or do I just need to memorize 38 different kinds of cysts/lesions..?
Figuring out what type of lining epithelium the cyst has is the first step. Then see if there are adnexal structures attached to the cyst. Then check your anatomic site. Those help narrow down the differential a lot and make it easier to search textbook to see what you are dealing with.
@@JMGardnerMD Thank you! that's a helpful starting point.
Warty dyskeratoma and SCAP looks similar , is lack of plasma cells the difference?
Presence of Plasma cells is one difference. But in SCAP The spaces are truly ductal/glandular. They are lined by double layer cuboidal to columnar epithelium often with apical snouts. In warty dyskeratoma, the spaces are not truly glands or ducts but rather are the result of acantholysis and dyskeratosis. You will see corps ronds and grains (dyskeratosis) in warty dyskeratoma but not in scap. I have more videos about both entities here kikoxp.com/posts/5084
