What is inside the itching?
#dermatology ImageImageImage
The outer skin of the little lump is decapitated with a needle, revealing a small thorn. Then the rest of the spines are "combed" with the needle, scratching the skin. ImageImageImageImage
At some point, it will start to bleed. Use a nail clipper or similar to remove as many raised spines (or bits of them) as you can. ImageImageImageImage

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 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
