Just had one of these removed from the back of my right hand recently & had 5 stitches that were taken out yesterday but the report i got from the doctor telling me what it was told me very little so i decided to research myself & found this informative interesting video, thanks.
hello dr .I am from Bangladesh ,,,,My sister develops pdfsp (bednar tumor),,,,on her upper wrist and by surgical removal it is ok,,,,,,,she is cured for 14 months more and mole stated 14 months ,total 28 months ,,,is there any possibilities to local recurrent or metastasize.Thanks in advance.
Soo informative. Everytime i plan to study a topic. I decide to go through ur videos first and add the pearls in my book. Waiting for DFSP video. Thank youuu for ur time and effort.
A most informative and practical video, much appreciated for your effort and time. I hope to see more of these mini series in the future, they are easy to digest, more focused and intensely useful.
I think I have this on the middle outside of my thigh. I wonder if my early severe sunburns as a child and a recent one later in life triggered it. Occasionally it is very itchy and annoying. I tried to scratch it off but what happens is the thin, smooth "dome" of surface skin scratches off, bleeds but eventually just heals around the bump.
i cant believe that in 2020 still no solution for dermatofibroma i have that ugly thing on my brest and dermatolgist told me tha the scar would be worse, it really depressed me
They can be cured by surgical removal but yes it will leave a scar. If you would prefer having a scar instead of a dermatofibroma, I think that is your choice as a patient. Also, the only way to be 100% sure it is actually a dermatofibroma is to have it biopsied or surgically removed and then examined by a pathologist under the microscope. You might consider discussing it again with your dermatologist and explaining how much it bothers you, or you could seek a second opinion from a different dermatologist (Mohs surgeons are dermatologists who specialize in skin surgery) or a plastic surgeon. Best wishes for healing and good health.
scar wont be worst , but they consider it comestic so you will have to pay out of pocket but the cosmetic dermatologist wont tell you it will be worst only the health plan doc that wont pay for it LOL
Im curious to know if you have read the recent articles about using HMGA1 and 2 immunohistochemistry to diagnose difficult cases of dermatofibroma vs DFSP and what is your take on that immunostain
No I haven't read those articles yet. I find that H&E can distinguish DF vs DFSP in the vast majority of cases. CD34 helps when they are difficult. And when really difficult, I just do FISH for COL1A1-PDGFB (if negative I reflex to PDGFD). Hope to make a DFSP video eventually.
I think I have one of these on the back of my shoulder, the bump has been there a while, it’s gotten a little bigger over the years and the color is getting darker.. I want to get it removed
Many different skin diseases can closely resemble one another. If you have any concerning/changing/growing skin lesion, please see your dermatologist. They can help you decide if it should be biopsied or surgically removed so that a pathologist can examine it and diagnose it.
They removed one from my back a year ago to analyze it and they said it was a dermatofibroma and now it has grown back, is it normal for it to grow back?
Haven’t watched this whole video since I made it. But I don’t recall including any cellular DF. I was waiting to do a different video on that as it’s a bit more complicated.
Do dermatofibroma slightly grow up not drastically but minimum. Got it checked my derm said dermatofibroma.. but it tends to itch and have a stingfeeling
Yes dermatofibromas can grow. Sometimes even grow quickly. If it is hurting or bothering you, please tell your dermatologist and ask them about having it removed. Usually small dermatofibroma can be easily removed with a punch or shave biopsy or small excision. Please discuss with your dermatologist so they can figure out what is right for you. Best wishes for health and happiness.
@@JMGardnerMDhi, I notice mines also itches and tings as well. I’m wondering the same thing.. mines have been on my skin since march it’s at 2 1/2mm got it checked by derm said it was dermatofibroma. If it were cellular would it have grown more than 2mm within months? If the itches and sting still there and doesn’t bother me is that a cause of concern still?
It's really annoying if u don't know what it is, which gave a lot of stress that thought it was melanoma or Basal, I just went to my dermatologist this morning and has checked out , TOld that I don't have to worry about coz it's a benign tumor, and don't need treatment at all otherwise the scars would be worse.
Can this be treated with imiquimod cream? Can a biopsy be suggestive of dermatofibroma but in reality to be basal cell cancer? Can a biopsy miss skin cancer? I would be very happy if you can answer this questions! Thank you
I only diagnose skin disease, I don’t treat it. So I’m not an expert at treatment. But I’ve never heard of imiquimod being used to treat dermatofibroma. And logically to my mind it doesn’t seem like it would be likely to work. But you should ask your dermatologist about the best treatment options for you. Usually dermatologist can diagnose dermatofibroma by physical examination. Sometimes a biopsy is performed to determine if it is a dermatofibroma versus something else like BCC or other skin cancer. Once a diagnosis of Dermatofibroma is made, additional treatment is not usually required because they are benign (unless the Dermatofibroma is large or painful or otherwise problematic, in which case it can be surgically removed if needed). Dermatofibroma can occasionally mimic BCC microscopically (it can cause benign hair follicle growths over it that look like BCC), but the reverse is not true. BCC doesn’t look anything like Dermatofibroma under the microscope. I suppose there could be some rare exception I’m not thinking of but I can’t recall seeing a case like that. Yes a skin biopsy can miss a skin cancer, either because the pathologist didn’t recognize it or because of a technical issue with the biopsy (too small, not deep enough, etc) but this is relatively rare overall in my experience. In general, skin biopsies are a very useful tool for diagnosing skin lesions. All of this is just for general information and it’s not medical advice of course. Please be sure to see your dermatologist to discuss any questions or specific advice related to your own healthcare. Best wishes for good health!
I don’t believe I’ve ever seen a dermatofibroma show up on the labia in the way you describe. I’ve never heard of clotrimazole (an anti-fungus medication used for fungal skin infections) being used to treat a dermatofibroma (which is a benign skin tumor that has nothing to do with fungus). But I cannot diagnose you or give you official medical advice since I am not your doctor. Please ask your doctor for further clarification and guidance. For myself and my family, I choose to only see a dermatologist when I have a skin problem, as they have the most experience and training in handling skin issues. Best wishes to you for good health.
Freezing usually works best for very superficial things near the top of the skin. Dermatofibroma is not usually treated by freezing (liquid nitrogen) as it is too deep to be reached by the freeze. Be sure to see your dermatologist to discuss what treatment options might be best for you if you have a dermatofibroma that you wish to have removed.

Glad you enjoyed it! Yes dermatofibroma is pretty common. I have a tiny one on my own leg actually!

Great video Dr Jerad!! Thank you for showing the many faces of dermatofibroma!!!
Very helpful Jerad ! from a skin cancer doctor in Western Australia
I have Seen a lot of your vidéos....they all are very instructive ans very useful in practice....thank you very much
Thank you so much. Each and every video is so helpful. Thank you for all the efforts. We enjoy each and every video of yours

patoloji ile DF'yi belirlemek basit midir? genellikle ek işlem gerekir mi?
Patoloji ilgimi çekiyor ☆
Awesome video as always!!I think I am learning pathology all over again!! Any hints to rule out Benign fibrous histiocytoma ?
Thx! Dermatofibroma is the same thing as benign fibrous histiocytoma. They are just two different names for the same entity.

Superb..

They screwed up, didn't remove everything.
Excellent thank you! Would some of the examples be considered as Cellular dermatofibromas?
Haven’t watched this whole video since I made it. But I don’t recall including any cellular DF. I was waiting to do a different video on that as it’s a bit more complicated.
I have what appears dermatofibroma
But have 8-10 mitosis / 10HPF
What is your mitosis threshold from your experience

@@JMGardnerMD Is it still cause for concern if it stings? If not I’ll leave it be if it is then I may have it surgically removed..

Hi have you produced the video on DFSP yet? Thanks
No not yet. Hopefully soon!
@@JMGardnerMD Looking forward to a DFSP video
Thank you so much!
awesome!

What causes dermatofibroma?
My Dr said I had dermofibrome I want to make sure
Thanks alot
Any special pattern for HIV associated dermatofibroma ?
Not that I’m aware of.
What is exactly a storiform pattern?
I’ll try to make a short video about this. Thanks for the idea!
Why do you think my dermatologist treated this with steroids knowing results would be poor?
Could I freeze this off?
Freezing usually works best for very superficial things near the top of the skin. Dermatofibroma is not usually treated by freezing (liquid nitrogen) as it is too deep to be reached by the freeze. Be sure to see your dermatologist to discuss what treatment options might be best for you if you have a dermatofibroma that you wish to have removed.
Jerad Gardner, MD if this is the case why do they recommend freezing warts, also why do physicians not just automatically excise them?
Dr gave me a clotrimazole cream for the bumps
My df came back after a shave.
