FINALLY clinician’s have figured that the PSEUDOSCIENTIFIC term “squamoproliferative lesion” means nothing more than a proliferating squamous lesion 🤣
#dermpath #dermtwitter #pathtwitter #dermatologia #dermatology #dermatologist #histopathology #dermatopathology Image
Squamoproliferative lesion was invented by some hotshot pathologist pretending its a diagnostic entity, but it actually means nothing more than an unspecified and unqualified proliferating squamous “lesion”.

#dermpath #dermtwitter #pathtwitter #dermatology #dermatopathology
Viral warts, seborrhoeic keratosis, actinic keratosis, keratoacanthomas, in situ and invasive squamous carcinomas are ALL either benign, atypical or malignant “squamoproliferative lesions”

I suppose it’s obvious where the diagnosis is headed… ImageImageImageImage
I only did 3 stains, probably could have used just 1, but with the lack of history I guess it felt right to super-prove it . ImageImageImageImage

The mean time period between development of a wound to malignancy is 30–35 years.

The most common malignancies seen in Marjolin ulcers are squamous cell carcinomas, but basal cell carcinomas and melanomas have been reported.

Two images to think about in this diagnosis.
What tips can we list in these two images?
What did I sign?
Next step?

#dermpath #pathology ImageImage
1- In these images, I want to draw attention to two tips. First, that there is a combination of patterns (Lichenoid + psoriasiform). A combination of different reaction patterns should always make you think of syphilis.
2- Another tip is what I drew: Rete ridges. Dr Elston's famous quote for them is sexy ridges. Very characteristic of syphilis.
Next step: Thinking about syphilis, look for plasma cells.

Another case to discuss, Cylindroma on 91yo female abdomen. it’s multiple in dermatomal distribution with extreme pain. There is this nerve entrapment at the base of the section. Histology seems benign but somewhat infiltrated nodules at the base. Q below #dermpath #derm ImageImageImage
It is challenging to treat, and also a concern if this is malignant based on clinical behavior. I am suggesting to excise the prominent nodules with local radiation for the rest of small nodules in the region. Any other thoughts ?
This patient has no history of syndromic features, but she had to remove 2 ft intestines in the past(I couldn’t get the detail but assume obstruction or diverticulitis).

It's overdue. Time for a #dermtwitter #tweetorial on...


We're going to focus on presentation and work up!

#sezary #ctcl #medtwitter #onctwitter #meded #FOAMEd
Just a few years ago, Sezary Syndrome (SS) was thought to be the leukemic variant of Mycosis Fungoides (MF). We basically thought people had MF, it would keep getting worse, and then it would turn into SS.

Check out my old #tweetorial on MF here👇
But patients often present with either the classic SS exam (red all over, super itchy), or with MF. Some patients would progress from MF--> SS, but it's the minority. So it became clear these are two different processes.

For that reason, we've changed how we think about it...

Due to the current outbreak of monkeypox in Western countries, I thought it would be good to review the clinical and pathology of this rare disease. More below.
#monkeypox #pathology #dermpath #dermatology
Previously, monkeypox outbreaks were zoonotic from monkeys or rodents. The current outbreak is human-to-human. Currently, most cases are homosexual males with genital skin lesions.
Incubation period of 1-2 wks, followed by fever, headache, backache, and vomiting. Skin lesions start as macules, then vesicles, papules, pustules, and crusts.
