@Lyle Pedro Thanks for your reply. I got to the site on google and im waiting for the hacking stuff atm. Looks like it's gonna take a while so I will reply here later with my results.

[@izaiahmathew9076]

@Lyle Pedro it did the trick and I now got access to my account again. I am so happy! Thanks so much, you really help me out !

[@lylepedro6342]

@Izaiah Mathew Happy to help :D

[@pheebmcgeeb]

I am a doctor training in skin cancer medicine trying to wrap my head around dermoscopic/histopathologic correlations and no one has explained things as clearly as you! I'm so glad I found your channel. Thank you and greetings from Australia.

Ask your GP to freeze them. Best to get them when they're smaller, in my experience. Occasionally they come back in which case you can get them done again. Best to check w your insurance carrier to see if you have coverage. Mine allows 7 per year.

[@topher68]

nice, short, to the point videos ... attention holding, not boring, factual info ... much appreciated ...

[@rubeenabano4803]

Accidentally found your channel. It’s very good, u talk about stuff nobody teaches in led school. Looking forward for more videos. Thank You

[@Piertides]

Thank you for the visuals and medical interpretation. I have several, more than that, but a few that are causing distress. I told my derm they remind me of parasites, creeping out of my skin 😁 now that I’ve viewed these microscopic images, I’m more convinced of that. They are ugly, look and feel, and I’m quite disgusted with them

[@Milana-Milanaaa]

Thanks for the detailed explanation. Great video 👍

[@kksga5476]

I just discovered your channel. U have a new fan. U are doing a great job in medical education, Thank u and God bless u.

[@patcompton700]

How do you get rid of the things. They drive me crazy.

[@Ridersonthestorm8899]

I gently rub cucumber on mine , on the body of it and surrounding area and I find it shrinks and goes overtime

[@stevejm9942]

I had one on my face and got rid of it over night by putting iodine and organic castor oil on it and covering with a plaster. The next morning in the shower it became really soft and simply peeled off!

[@reetafareed4602]

Thank you much Dr., could you please explain briefly how pseudo and true are formed?? Thank you

[@NachiketaThakur]

Amazing sir. You are a genius.

[@amalabdelhafez2674]

Thanks for the short video. Please do this usually.

[@g.ioanaeliza7886]

First of all, thank you for all the quality content and all the work you put in those videos! I was reading about S.K lately and i had in mind this " macular SK".I've read it doesn't have many horn pseudocysts and its not even acanthotic.... and in the pictures from internet, it looks rather flat and i don't know how to rule out such an entity.Do you encounter in your practice such macular SK and what are the features that help name such a flat lesion as SK?Thanks! *ps : not clonal SK, which has nests.But flat, bland lesion that has no other features suggestive of SK.

[@alaaal-musallam3797]

Great as usual 🙏🏻

[@MedManiac1]

best video for dermatology🤩⭐

[@manu1166662222]

Nicely explained 👌

[@dianac2498]

I’m glad to hear they can be dark in color as these black globular things come off when I do my anti fungal shampoo. I take a pic with a smart phone and they are icky. I wash y hair every single day so I knew it wasn’t dirtI’m so happy I found this video. Can this stuff get in your hair strands? I notice stuff coming out of hair strands - as if it had little cells that hold the dandruff maybe? Ugh. No more sugar. Have to get rid of this stuff.

[@dr.deathium4487]

Thank you very much for your videos. I wonder though, which camera are you using for your videos? Do you just attach the camera to the microscope and record?

[@RaulRodriguez-sh6vb]

Perfect explanation. SK is quite common

[@mabelguerrero5001]

Thank you so much!

[@maramjassem8781]

Your the best 🌸

[@reenamerad]

Thanks a lot, Jerad. How would you differentiate this from a viral wart, when it is acanthotic and papillomatous with parakeratosis, as in the last case in the video?

[@JMGardnerMD]

They can be pretty similar to wart in some cases. If they have in toeing of rete, large coalesced granules, spires of parakeratosis over tips of papillary surface projections...those things make me favor wart. If I can’t decide between wart and SK then I just try to pick one, usually favoring whatever the dermatologist wanted. Wart vs SK usually doesn’t matter for purposes of patient care so I don’t get too worried about it if I can’t decide. ‪my #dermpath Survival Guide discusses how I handle this and other diagnostic difficulties in more detail : bit.ly/2Te2haB ‬

[@katherinecorrell4817]

Thank you. I’m not a derm student, but I am always curious as to what things look like under a microscope! Especially if it’s growing in my body-yikes!

[@tamilarasirenganathan8243]

Thank you sir. All your videos are very helpful. I have a question. How to differentiate clonal seborrheic keratosis from intradermal nevus?

[@JMGardnerMD]

Clonal seborrheic keratosis is in the epidermis and Intradermal nevus is in the dermis. My nevus video may be helpful: kzbin.info/www/bejne/oHy9daSAmt9soNk

[@hagarkhallaf991]

Thanks a lot

[@eishasoomro8185]

Hello sir ,thankyou for the wonderful video..could u plz explain difference between true horn cyst and pseudohorn cyst?TIA

[@JMGardnerMD]

kikoxp.com/posts/2302/public

[@eishasoomro8185]

Fantastic 👍

[@pathologysimplified2821]

Can squamous cell carcinoma arise from these. I had a case both of these coexisting

[@JMGardnerMD]

Yes. Uncommon but it happens.

[@RaulRodriguez-sh6vb]

How to differentiate with verruca? Because of the pseudo horn cysts and also the pushed out from the surface?

[@JMGardnerMD]

Those are both helpful clues for SK vs Verruca. Some cases overlap a lot and for those I call them “verrucoid keratosis”. You might find my Verruca 101 video to be helpful: kikoxp.com/posts/6126

[@RaulRodriguez-sh6vb]

Thank you

[@emileel3196]

With these slides, are we seeing a cross section of an entire keratosis? The keratosis has been removed, and a sliver of it is viewed under a microscope, correct?

[@JMGardnerMD]

Yes, exactly. It’s been removed and then we are looking at it cut straight down through the middle.

[@FashnKween]

What causes this? Is it virus related?

[@SR-yg5cg]

What is verrucous keratosis , same as sk?

[@JMGardnerMD]

I don’t use that term very often. But some people use it to describe lesions that have overlapping features between seborrheic keratosis and verruca.

[@SR-yg5cg]

Therefore a viral wart?

[@emb74]

Sure would be nice to see what he’s actually talking about instead of microscopic level slides.

[@dawalpeer5852]

Treatment medicine name

[@katherinecorrell4817]

Although it pushes up from the skin, it sure does look like a parasite with a tail!

[@Piertides]

I have said these remind me of a parasite. I have several inflamed ones and they feel like a parasite arising from the skin layer. Cause of anxiety in me.
