Dermoscopy expert videos on YouTube

I have just posted this learning aid out to the doctors and nurses on my course at present. It costs me nothing to post it here too. Lots of brilliant expert teachers have put very useful dermoscopy videos on YouTube. Excellent resource, and free. Share and enjoy.


>>Many of the world’s top dermoscopy teachers have taken the trouble to post presentations and lectures on YouTube. I strongly recommend these ones linked below, you will find others. I have put links to a few of the best here, please have a look and if you can, mark the video up and leave a positive comment.

I have mostly put up simpler videos for beginners, some of them are more challenging. If anything is difficult, do the easier ones first and then return to the more difficult ones later.

PLEASE NOTE there is inevitably a subjective element in dermoscopy/dermatoscopy and different teachers have different styles and emphases, and there is some conflict of terminology still. Do not worry. As you learn from many teachers, it will all come together and make sense.

benign naevi reticular pattern Iris Zalaudek Iris’s short videos are particularly ideal introductions to the basics. Watch them all twice.

Giuseppe Argenziano of Naples has published about a quarter of the world literature on dermoscopy, he is a very able speaker, anything of his is worth viewing.

Harald Kittler of Vienna has advanced a new descriptive terminology which rationalises the terms we use to describe dermoscopic features. This descriptive terminology is slowly replacing the older metaphoric set of terms. He also pioneered the ‘chaos and clues’ pattern analysis approach.

The myth of dysplastic naevi-as above, you may prefer to leave this until later . But it is important-Professor Kittler presents strong evidence that the term ‘dysplastic naevus’ is misleading and should be abandoned.

Ian McColl, a Scots dermatologist now working in Australia, has made a number of 10-15 minute videos where he talks though cases in detail, mainly using the Kittlerian descriptive terminology. Rewarding. I have put links to a few, more will suggest themselves as you watch. Enjoy.

Please dermoscopy learners, watch these videos and click ‘like’ if you do. These videos get a shamefully small number of likes-these are top world experts, all of them better than me, and they deserve credit.

International Dermoscopy Refresher and Update, Wednesday 28th November 2018, Fareham, Hampshire. Now booking.

 International Dermoscopy Refresher and Update day conference

Wednesday 28.11.2018, Holiday Inn, Cartwright Drive, Fareham, Hampshire PO15 5RJ
This is a dermoscopy refresher and update course with an international flavour, for dermatologists and all clinicians who regularly use dermoscopy to evaluate suspicious skin lesions in hospital or community. Basic knowledge is assumed-doctors and specialist nurses wishing to make a start with dermoscopy would be better advised to attend an introductory course.
Stephen Hayes, Catriona Henderson and Birgit Pees are keen dermoscopists with over 50 years combined clinical experience, who have taught an annual dermoscopy course in Fareham since 2011. This November, we are delighted to welcome Professor Luc Thomas from the University of Lyons, France, one of the most published and respected authorities in world dermoscopy. He specialises in skin cancer with a particular interest in nail unit disease. He has agreed to present on the dermoscopy of pigmented and non pigmented nail unit and foot lesions, also to briefly discuss the use of dermoscopy in France and teach us on some didactic and challenging cases from his practice in Lyons.
All presentations will be richly illustrated with many dermoscopic cases studies. It is hoped to make PDFs of presentations with images available to delegates for private study, subject to permissions.

A new red lump on the skin

This new, firm, pink lesion appeared over several months on a young-middle aged person’s neck. This is a ‘red flag’ presentation. I used to argue with a very senior skin cancer specialist who shall be nameless about the merits of teaching dermoscopy to GPs. He said I shouldn’t bother, but instead teach them about the danger of the new, growing pink nodule (which can be a deadly non-pigmented melanoma). He said there was no evidence for the benefits of teaching GPs dermoscopy. I then referred to a couple of peer reviewed papers, and he got a bit cross, sort of ‘Young man, when I say there is no evidence, HOW DARE YOU contradict me by producing some evidence!?!’  I told him that I would take half of his advice-carry on teaching dermoscopy, but whenever I did, mention the danger of the new, pink lump-which is sometimes a non pigmented (amelanotic) melanoma. Anyway, back to the case.

case 10 (1)

Can you tell what it is? Yes you can-it’s a dark pink lump. But that’s all you can say. Could it be a haemangioma? not impossible on this view, but it’s a short history. Also, on palpation it was firm, not soft and compressible which haemangiomas are. Time for dermoscopy.

case 10 (2)

The dermoscope immediately rules out haemangioma. Nothing like, no chance.

let’s apply SCOPE (*).

Symmetry? of shape and outline, yes, but for colour and structure (way more important) not at all

Colours-how many? I see red, white, brown and black. No way is that acceptable.

Structures-how many? I see shiny white structures, brown globules (1 o’clock to 3 o’clock border) and featureless brown-black border 10 to 1 o’clock) plus irregular vessels. Too many structures.

Edge. The edge is smooth, but rim of dark featureless + brown globules from 10 to 3 o’clock.

Chaos and Clues would also excise this lesion, as would the the two step algorithm. Step one-melanocytic or non melanocytic? It is judged melanocytic, because of brown globules, and by default as we cannot make it anything else (e.g. BCC, wart, haemangioma, dermatofibroma, etc). Step 2-could it be a melanoma? Yes, as it is chaotic.

The lesion was excised immediately and reported as a MUMP, a melanocytic lesion of unknown malignant potential. In plain English, this is an abnormal proliferation of melanocytes which the histopathologists can’t quite come off the fence over. It’s neither a normal mole nor a definite melanoma. The consensus is that you treat it as if it was a melanoma, which we did.



Beware the new, firm, growing lump.

Look out for pigment at the rim of pink nodules, it may be a clue to hypopigmented melanoma.

Irregular brown globules in a lesion like this are highly suggestive of a hypopigmented melanoma.

If in doubt, refer or excise. This was a ‘MUMP’ but could easily have been a nodular melanoma.

(*) SCOPE is a crude mnemonic invented by Dr Catriona Henderson and myself. Based on a slide Dr Henderson produced, to simplify lesion evaluation. It has not been independently evaluated, but we find it helpful. It overlaps very much with ‘chaos and clues’ given that ‘chaos’ is defined as multiple colours, multiple patterns.

The battle continues

Alethea’s last post, just before she died from melanoma. So sad. This is why it is worth working constantly to improve the skin lesion diagnostic skills of all health care practitioners, especially GPs.

Me and Melanoma

So, recently lumps have appeared around my body, one on shoulder , two in right boob, one where my ribs are and one in my upper right bum cheek.  The one above shoulder needed removing as it was growing so I am currently waiting for the results.  They think its metastasis but we aren’t sure.

I’ve also been experiencing the worst stomach/tummy pains ever.  They have made me vomit on occasion too. So Wednesday I was checked in to the local general hospital where they gave me blood tests and a chest and abdomen CT scan and x-rays.  They said it may be crone’s disease, then that its an ulcer, then that its metastasis and that I will be needed intravenous chemo.  Needless to say I was devastated.   Then I checked out of the hospital and went to see my doctor who checked the CT and he said he said…

Feedback from South Coast Dermoscopy course

We haven’t done the full feedback analysis yet, but here was this unsolicited email from a participant (see below). I include this not so much as a ‘boast post’ but to illustrate that our integrated skin lesion recognition and dermoscopy course tries very much to familiarise learners with the appearance of  harmless skin lesions. This is very deliberate, since nearly all the moles people ever ask their GP to look at are going to be harmless. Yet every day in clinic I see patients with (to me) obviously harmless skin lesions who have been needlessly sent on an urgent cancer pathway and are in a panicky state as they are afraid they may have a dangerous tumour. That’s one of the things I love most about dermoscopy-the power to reassure. There is no getting away from the reality of melanoma-which kills 6 or 7 people a day in Britain-a certain amount of fear is appropriate, same as with children and road safety. Good GP dermoscopy skills can relieve fears, which is human and compassionate,  and also more efficient in terms of optimum health care resource management.

I teach that doctors need to get skilled, confident and safe to determine a mole is harmless, then don’t just say so but explain why, and use the consultation to advise about sun protection and the signs of a dangerous mole. At the same time, it’s vital not to miss a melanoma, so we also post LOADS of cases of melanoma. The memory drive and on line case discussions over 12 weeks further reinforce such lessons.

Next year, we are thinking about altering the course, maybe running it as a one day course twice a year, as I had to turn a lot of learners away since they couldn’t make the 2 half days. If any previous learners have any views on this, please comment. The USB stick and 12 week on-line tuition will remain.

PS a prospectus and booking details of our International Dermoscopy Refresher and Update day conference on Wednesday 28th November will appear here soon. It will be at Holiday Inn Fareham as usual and will feature Professor Luc Thomas, acclaimed world expert from Lyons, France presenting on foot tumours and perhaps some of his many international research publications as well as reports from the 5th world dermoscopy congress to be held in Greece this June, plus other goodies. This course will not be for beginners but should delight those with some experience and prior learning in dermoscopy who want to refresh and update.

Hi Stephen

Just a note to express my appreciation of the course on Friday
Well organised and well presented it was all I anticipated. The usb stick is a particularly good resource.
The email cases are also stimulating.
Surprisingly perhaps I found the parts on non malignant lesions most helpful. It’s only natural that as specialists you spend you energies on melanoma but as a gp I see mostly benign lesions with only 2-3 melanomas per year on the practice population so I found the positive identifying features of benign lesions to be helpful rather than my usual practice of simply excluding sinister features.
Best wishes

ENTRY CLOSED FOR this year’s Integrated Skin Lesion Recognition and Dermoscopy course


I look forward to meeting this years learning group on Friday at Fareham.

Details of further courses will appear here soon, including an international dermoscopy refresher and update conference on Wednesday 28th November 2018. Also, as I am running an on line course over the next 12 weeks, more new cases will be being posted here.

For 2019, I am looking at a reboot of the course, perhaps run it twice as year (spring and autumn) with a one day conference at Fareham instead of the 2 half days, a password protected web site and more on line and directed learning. The views of any past or potential learners would be most welcome. How can we do better?

kind regards
