I have been watching all of your 'Basic Dermpath Cases' videos so far. They have been incredibly useful to me as a trainee. Thank you so much for taking the time to record these high quality teaching videos. I can't get enough of them!

[@ningsickdoc]

When i see "Jerad Gardner", i press "Like", Awesome work as always sir!

[@kinludovico]

deeply grateful for the awesome lectures :) Thank you very much, keep going doctor Gardner. It's our duty to motivate our colleagues to learn dermatopathology. Through your made-simple lectures they will hopefully do ;)

[@nehapop]

Thank you so much for taking the time and trouble to do these videos. They are so useful!

[@abs0292]

Thank you so much for these awesome videos! I am taking a dermpath elective now and am finding these videos SO SO SO helpful!! Please make more videos (especially for different types of moles, lentiges and melanoma diagnosis!)

[@ZainMehdipathology]

Thank you, very much for explaining these cases. I am a speciality doctor in pathology preparing for FRCpath 2. I would really appreciate if you can do a video on common bullous lesions. Thanks.

[@woloabel]

As is typical in all of the lectures, an exquisite and insightful treat of medical knowledge. I bid Mr Gardner a grand practice and even more accolades from fellows and civilians. ...Dermatopathy is a grander concern in an industrialized, first world society. It is indicative of its true wealth, as grandest success is in he who accomplishes large economic feats coupled with the health and sanity to relish such....

[@minetteking7]

Thank you very much.

Thanks. Lovely videos

[@julianathomaz142]

Dear Jerad, your videos are amazing! Thank you very much for share your knowledge with us! I hope you can come back to Brazil in our next Congress! Best Regards!

[@JMGardnerMD]

Obrigado! I can’t wait to come back to Brazil! I love your country and your awesome pathologists 😊

Nicely informative videoes Great thanks 💐💐💐

[@essambasha-dv3hb]

Very nice

[@DrAppy01]

haha !! amazing! i love your sense of humour and the jokes that we hear throughout the video. :P

[@JMGardnerMD]

Thanks. Most of them are pretty nerdy jokes, but I just can't help myself. ;-)

[@amanatsoomro4512]

You are super awesome 😍😍😃

Small cell lung cancer and merkel are treated exactly the same, so no need to differenciate. Thanks for high quality lecutres, im an oncologist btw

[@JMGardnerMD]

Thanks for the kind words and the comment. Do you mean the chemo is the same for both Merkel and small cell? I've read that Merkel often responds well to checkpoint inhibitor drugs whereas small cell carcinoma doesn't respond very well to them. But I don't know much about specific chemo regimens. Surgically they seem to be managed differently at least in the institutions I've worked at. Merkel is usually treated with wide local excision and sentinel node biopsy but I wouldn't think metastatic small cell carcinoma in skin would be managed that way (but I've only seen a few cases, so not sure if there is a standard). Solitary skin metastasis of melanoma is managed by surgical excision with narrow negative margins, so I would suspect other metastatic tumors would receive similar treatment. Perhaps this management varies between institutions though.

[@pavelboico9283]

@@JMGardnerMD Thanks for replying. Systemic therapy is the same. I don't know whether check point inhibitors perform better in Merkel cell carcinoma, nor it does matter. In both cases we use chemo plus check point inhibitors as a first line treatment, access the response and go from there. Concerning local treatment - in both cases we perform PET/CT to exclude note involvement and metastases. If it's local - we will do surgery, whether it would be lobectomy or wide excision. Or radiation therapy. So, for me, Merkel and SCLC are really the same disease at least biologically

[@bogdantoma6927]

@@pavelboico9283 They are rather far from being the same disease from a tumour biology standpoint... for one I don't know that oncoviruses cause small cell carcinoma, whereas they do cause MCC (at least the majority of cases).

[@pavelboico9283]

@@bogdantoma6927 thank you for your input! I didn't know that and it's really interesting

[@mayssaakabeel9847]

Thank you very much. . I wish you can divide them to short videos, one for each case.

[@JMGardnerMD]

If you look in the video description, I list each diagnosis with a link to the part of the video where it is discussed. Click that time stamp link and it will take you directly to that section of the video.

Great work Professor

[@SandhyaRamachandran]

awesome Jerad...really appreciate ur time n effort! at 35:13 almost mistook it to be a nevus at LP ...a neurotized nevus if you will ! how does one differentiate?

[@JMGardnerMD]

Neurotized nevi usually have at least focal areas with round/epithelioid cells or nests. Usually superficially. If you really wanted to know, you could use MART-1, which would stain nevus but not nerve sheath tumors. However, as both are benign, I rarely do this.

[@SandhyaRamachandran]

hmm...thank u.

[@ser_Gallius]

Very informative videos and so good explained. Please can you do a video on melanoma ?

[@JMGardnerMD]

Yes, I am planning to do this once I find time.

[@SandhyaRamachandran]

do u hv one on inflammatory dis of skin please ?

[@JMGardnerMD]

Not yet, but plan to in future. Check out these videos by Raj Singh: kzbin.info/www/bejne/pJKql6lti5ZmgJo & kzbin.info/www/bejne/pIm6qp59bLeDapI. Also we cover a lot of inflammatory dermpath in our 4 hour dermpath board review video: kzbin.info/www/bejne/h2mbqneLYrWsn9U

this looks to be a treasure chest...will open over the weekend !!:) tanx a lot
