Thank you very much for sharing high yield histopathology topics. Please make deep fungal infections series and also interface dermatitis diseases. Thanks a lot! :)
I had a spiradenoma removed last year at age 36 (appeared age 28). When it first appeared it looked like a bug bite, just didn’t go away, a few years later it started to turn silver/grey. Doctors told me not to worry, that it was a Dermatofibromas. Fast forward 3 years and I started having inward pulling sensation where the now blue/purple bump was. Within a week of this “pulling sensation” starting it had doubled in size. The pulling sensation became a sharp sudden stabbing pain that was sporadic and without instigation. Again i saw my doctor and asked for a biopsy. He agreed that the pain was unusual- and I requested the whole thing removed for biopsy. During removal, he remarked that it was deeper than he had anticipated and had small blood vessels going to it, therefore he was more concerned about what it was. Pathology indicated it was spiradenoma. Now I wonder why tumor suppressor genes didn’t stop this from growing- so here I am. This is a great video!
Thanks Dr.Gardner for your high-quality videos. It's really a precious resource for a pathology resident like me. One question, the last spiradenoma case you're showing (of the first series of cases, around minute 10:00), couldn't it be a Squamoid Eccrine Ductal Carcinoma (SEDC), too? I've seen a couple of them recently and I see some similarities. Thanks again. Dr. G.M.
My pleasure! That case at 10:00 doesn’t look like my concept of squamoid eccrine ductal carcinoma. May be hard to see on the video but it’s actually a circumscribed nodule that has lots of background edema. Gives the false appearance of infiltrative growth but actually those nests and cords are all within one large circumscribed mass. The squamoid eccrine ductal carcinomas that I have seen looked a lot like infiltrative well diff SCC but they had duct formation (and one of them had LVI which is pretty unusual for cutaneous SCC, which is what made me look into it further and realize I was actually dealing with squamoid eccrine ductal carcinoma instead!).
Thank you so much Jerad, very helpful video, all three skin nodules of spiradenoma we so far biopsied were very tender and both the two cylindromas we had were not tender, can that assist in a way, of course if there is no collision of spiradenoma/cylindroma,
To me the most helpful thing is that adenoid cystic usually has very sharply circumscribed “punched out” glands filled with mucin creating cribriform pattern.
Great video as usual. Totally enjoyed learning these entities. Can you please do couple of videos on melanocytic lesions.. SPITZ NEVUS to begin with... Thanks a ton 😃
We have a dermal axillary tumor with clear cell hidradenoma features and some papillary formations resembling hidradenoma papilliferum. Does hybrid tumors represent like our case or is it just clear cell hidradenoma?
Hidradenoma is a different family of sweat gland tumor. It is not related to spiradenoma/cylindroma. There are a handful of different sweat gland tumors that have papillary features. In axilla one must also consider possibility of breast proliferation arising in ectopic breast tissue. Please take some pics and share them in McKee derm group on Facebook so everyone can see them and comment on them.

Super helpful video, thanks Jerad!
thankyou so much doctor JERAD... U DESERVE TO BE THE BEST PATHOLOGIST...CONGRATS Dr Gardner
Thank you for this explanatory description and comparison.
A very good explanation and differentiation of the two conditions. Thanks,
Dr Jerad
You are a great teacher. Thank you so much. Really appreciate your efforts.
Thank you!
Thank you for the awesome vedio
can you pls post vedio on Trichoblastoma when possible
Thank you very much for sharing high yield histopathology topics. Please make deep fungal infections series and also interface dermatitis diseases. Thanks a lot! :)
Ur videos are wonderful..can u pls post videos on neoplastic lymph nodes..I mean lymphomas
Thanks for great presentation, Could you please post video on hidradenoma and its variant. Thanks
Yes, also on my to do list

thank you so much! please can you explain how to diagnose a MPNST and synovial sarcoma.
Great idea for a topic. I'll work on getting video made on those entities.

@@JMGardnerMD As always thanks for your precise and kind answer. All the best! :)
Thanx for the amazing simplified explanation
Thank you for your awesome video. It's very helpful and clearly explained topic.
Thank you so much Jerad, very helpful video, all three skin nodules of spiradenoma we so far biopsied were very tender and both the two cylindromas we had were not tender, can that assist in a way, of course if there is no collision of spiradenoma/cylindroma,
Dr Gardner, would you please give us some clues to distinguish cylindroma from primary cutaneous adenoid cystic carcinoma. Thank you very much.
To me the most helpful thing is that adenoid cystic usually has very sharply circumscribed “punched out” glands filled with mucin creating cribriform pattern.
Thanks. This video has been useful for my practice.
Amazing. More please.
Thank you
Great video as usual. Totally enjoyed learning these entities. Can you please do couple of videos on melanocytic lesions.. SPITZ NEVUS to begin with... Thanks a ton 😃
It is on my to do list. I'll try to get it done sometime soon
Thank you very much
Thanks for the detailed explanation. Plz sir can you include other systems too.
Sorry I only do skin bone and soft tissue pathology routinely in my practice.
@@JMGardnerMDAnd that's great. But if you could include some classes like the Lymph node class it would be really helpful sir.
It was very helpful. Thank you sir. 🙏
Awesome, thanks alot, God bless u
Excellent
Plz explain all skin appendageal tumours sir
It’s on my to do list
Excellent sir....we want more 😀

I hope to make video soon on hidradenoma/acrospiroma family of sweat gland tumors.
Thank you Sir
awesome
wow!
👍👌👌👌👌 addicted to your videos.. thank you so much .. i learn a lot from you sir..
Here's a duct, there"s a duct, everywhere you look there"s a duct! DUCT!
Thanks
duct tales
Thank you sir
