Basic Dermpath Cases - Explained by a Dermatopathologist

A complete organized library of all my videos, digital slides, pics, & sample pathology reports is available here: kikoxp.com/posts/5084 (dermpath) & kikoxp.com/posts/5083 (bone/soft tissue sarcoma pathology).
I came across all of these random cases during about 1 hour of a routine dermpath sign out session recently. This is a nice sample of the kinds of biopsies a typical dermatopathologist sees in practice. I discuss my thought process for each case. Huge thanks to Abigail Cline, a medical student at Medical College of Georgia, for volunteering to type a transcript of this entire video so that I could provide closed caption subtitles.
Entities discussed:
Seborrheic keratosis (0:00)
Neurofibroma (7:07)
Pilomatricoma/Pilomatrixoma (14:07)
Grover's disease (transient acantholytic dermatosis) (19:49)
Trichilemmoma (23:56)
Fibrous papule (angiofibroma) (27:15)
Intradermal melanocytic nevus (36:00)
Squamous cell carcinoma (44:45)
Arthropod bite reaction (56:40)

I am a 1st year derm resident, and i am keep watching and learn a lot of things thanks to your valuable videos! You are the definetly great pathologist!

[@veramae4098]

KZbin randomly recommended these to me. Usually I get lost about halfway through, but I'm enjoying and learning. Thanks.

[@AndreaDArino]

I'm a resident in Dermatology in Rome and this video was absolutely fantastic! Really fascinating and illuminating! Please keep them coming!!

[@johnfazio2892]

This is excellent. If anyone wants to know what a Dermatopathologist does, this is it!

[@ivobuters8775]

Thank you Jerad, I am currently studying dermatology & skin cancer surgery as a mature aged doctor in Australia. Your dermpath video tutorials are extremely helpful and help to consolidate & broaden my existing knowledge. Well done, keep it up.

[@abdullahthayyil9878]

Dear Dr. Buters I am interested in studying Derm. Can you give me info how to apply to your institution.

[@olgademidova1]

Thank you so much for making these movies. I am a 1st year Derm resident studying dermpath. Your explanations are extremely helpful. Please, do not stop. All movies are great. :-)

[@Goloturiya]

Just starting to study dermpath as a dermatologist, after only 2 videos I could already recognize 2 of 4 cases from pathology department. Thanks a lot!

[@jsegalbts]

These are awesome videos! Thank you for taking the time.

[@jrfeliz90]

Another great video! Thank you for such wonderful educational material

[@Joisu121]

You're such a great teacher! You are the best!! Thank you so much! I'm a derm resident and your videos are so helpful. I hope you continue to make more.

[@JMGardnerMD]

Aw thanks! That's so nice to hear. I have 4 other random dermpath videos like this one and a bunch of other videos about soft tissue tumors and dermpath. I have more videos in the works.

[@Joisu121]

I will keep following. Thank you!

[@mahwashghani9720]

Wonderful video....of great help.thnku

[@Irene-mc7lk]

What a great video! Thank you and can't wait for the next one!

[@JMGardnerMD]

I have 4 other basic dermpath videos like this one. This video has WAY more views than the other 4, and I don't know why for sure. I assume it's because everyone thinks you have to start here since it is first? You don't! They are all random cases and don't need to be watched in order. So give the other basic dermpath videos some love, too. They are getting lonely! ;-) - kzbin.info/www/bejne/o56raoOZqK-Jfdk (cysts! plus Merkel cell carcinoma, keloid and hypertrophic scar, supernumerary digit/polydactyly, acroangiodermatitis - severe vascular stasis) - kzbin.info/www/bejne/gme6ZKibZZqnasU (dermatofibroma, glomus tumor, mycosis fungoides/cutaneous T cell lymphoma, ruptured folliculitis, epidermolytic hyperkeratosis & epidermolytic acanthoma) - kzbin.info/www/bejne/mpq7mmSEndlpgq8 (Demodex mites, warts, SK, biopsy site change with aluminum chloride, chromoblastomycosis, porokeratosis) - kzbin.info/www/bejne/jaCkmXtvbK6KfrM (tattoo reaction, lichen planus, SCC, lichen sclerosus, Grover's disease, abscess, inverted follicular keratosis, Mastocytosis)

[@JMGardnerMD]

Ah so you noticed that little bit? LOL. I try my best to keep things quiet around me when making videos. But sometimes things happen.

[@mincui3815]

Great video, and it is very thoughtful of you to include the list of cases. Thank you very much from a path resident.

[@JMGardnerMD]

Glad you like it! The list of cases also helps me keep track of which entities I have covered in which videos. :-)

Sir kindly upload such new vedios on dermopath cases. These wl help alot dermatology residents

[@bahaaibrahim9404]

Dr. Gardner, first of all thank you so much for putting the effort and hard work in this amazing set of dermpath lecture. While I believe this elite level isn't an overnight result. Could you please help us with the best resources that helped you to excel dermpath, I mean books? Thank you again, Bahaa

[@JMGardnerMD]

Here’s a good one for beginners. kzbin.info/www/bejne/l2HVoZtriJV3oac. For big reference textbooks I love McKee the best. For melanocytic lesions this book by Massi & LeBoit is wonderful: www.amazon.com/gp/aw/cr/3642373100/ref=mw_dp_cr. More textbook reviews here: pathinfo.wikia.com/wiki/Textbook_Reviews

[@armenkishmiryan]

thanke you

[@LEW_Aleha]

You are a genius

[@kevinmoreal5200]

Man this guy is absolutely amazing, such a help for my path rotations. Do you, or anyone, know of good lecture people/videos to watch for other path rotations? you know like anything from GI to gyne to lung. thanks!

[@JMGardnerMD]

Thanks! Here's a playlist I keep of representative videos from other pathology youtube channels. I keep adding to it as I find more so that my viewers can more easily identify other pathology channels on KZbin. kzbin.info/aero/PLkuwOd2JcINNP4tYdIwzA3v8wDYG1Eewi

[@operationgetthugs232]

Seborrheic keratosis: Horn pseudocysts are derived from pre-existing hair follicles.

[@KyrieW]

Thank you for uploading! Just a suggestion- can you group cases by topic such as "adnexal tumors" or "lichenoid inflammation disorders"? Thanks

[@JMGardnerMD]

I'm working on making more themed videos or videos about one diagnosis only. Here are my skin adnexal videos: pathinfo.wikia.com/wiki/Skin_Adnexal_Tumors. I plan to eventually make a page like this with links to all of my videos organized by disease/topic. Will tweet/FB it once I create it.

[@atmanfisal79]

Nice....

[@tamilarasirenganathan8243]

Thank you so much. I learned a lot from ur lectures. I have a question regarding verrucous lesion. Verrucae Vulgaris and condyloma acuminata are they both histologically similar lesions occurring in different locations? How to differentiate condyloma acuminata from verrucous carcinoma? Condyloma acuminata do not inward bending of rete ridges like verrucae vulgaris but broad pushing border like verrucous carcinoma. It's really confusing. Thank you for your help.

[@JMGardnerMD]

Condyloma and verruca have some similar features but they are different. Condyloma is more of a rounded “knuckle” shape on surface while VV is more finger like. Verrucous carcinoma is a complicated topic. Check out this free paper from our dermpath special issue of archives of pathology: meridian.allenpress.com/aplm/article/143/7/821/10085/Verruciform-and-Condyloma-like-Squamous

[@yasminsayed7699]

Is there is video of basic basic dermatohistology. Normal skin layers . And inflammatory cells?

[@JMGardnerMD]

Yep! kzbin.info/www/bejne/r4K0Y3ejr5lljNU

[@missknowall]

While I am a great follower, may I offer a suggestion? Can you please add the names of topics covered in a particular episode of this series. Would make it easier for us to refer to them again and again. Thanks

[@JMGardnerMD]

Thank you for the feedback. If you click on the video description, it will expand and show you a list of all of the entities covered. These also have timestamps that can be clicked to take you directly to that part of the video (the clickable time stamp may not work if browsing from mobile).

[@missknowall]

OK! Didn't know that. Thanks.

[@JMGardnerMD]

I just saw your nice review on my google business listing. Thank you!

[@azgonz56]

Medicine Gardner, bon travaille! Se fait la dermapathy très bien et extraordinairemente narrée. Vous devez devenir un bon maitre d'academie et je serai votre testimoigne.....

[@MrHirankr]

Nice routine cases, was really helpful. I liked the way you explained the features. Can I have your maid ID?

[@beenjammin8581]

Did you s100 stain that neurofibroma?

[@JMGardnerMD]

No. H&E only.

[@candicemathers1538]

Jared I feel the dermatology field is lacking when it comes to new diseases which they tend to diagnose nearly everything as a rash and give cortizone/roids. They are misdiagnosing thousands per day in my opinion. So excited after finding you on Twitter .

[@KingElrosTarMinyatur]

Dr Gardner, wonderful case session. Looking forward to the next in the series; I am really binging this weekend. At 53:11 One minor correction, it is the vermillion lip (not cutaneous lip) which has the higher risk of spread. I'm sure you misspoke. Thanks again. ascopost.com/News/58843

[@JMGardnerMD]

Thanks for catching that!

[@odeszarules5125]

Jerad, write a book already

[@JMGardnerMD]

Have one in the works. Planned to be released in late 2018 from Innovative Pathology Press (@InnovPathPress on Twitter...still working on website). It's a brand new publishing company founded by Elizabeth Montgomery. She's organized a series of "survival guide" style soft cover books for pathology. I'm writing the dermpath edition.

[@odeszarules5125]

You cannot even fathom how happy that makes me. You definitely have a knack for teaching. I will buy every single book you ever write!

[@missknowall]

Can't wait.
