EWSR1-NFATC2—associated sarcoma. NB: a very rare neoplasm, predominating in bone; anatomizing cords-to-sheets of small-to-medium cells; abundant myxohyaline stroma; RNA-seq useful in differentiating from potential mimics (Ewing sarcoma, myoepithelial tumour, &c).

So lovely to meet you in person, Dr. Maclean! I hope you enjoyed your stay here (and hope to see you again!) 😊

Last RT my students may be interested since we had just discussed autopsy on our last module 😄

#PathArt Sneak Peek#2 Enjoy these beautiful entries by our super talented and creative residents, fellows and faculty!

Who knew blueberries could teach us about healthy cells? 🫐😲. Today’s #IntroToPath, I use 'em to explain metaplasia (🖤 blackberries), hyperplasia, and hypertrophy 💪🏽. It's like a berry-licious journey through the world of pathology! 🌎#Path4People #BerriesForEducation 🍓🍒🔬

Sonic Hedgehog (SHH) signaling pathway... SHH binds PTCH1, leading to release of SMO (Smoothened), altering transcription and cell growth. Mutations in the pathway are involved in birth defects, basal cell carcinoma, Gorlin Syndrome, medulloblastoma, & other tumors.

As much as I love first-generation neuroendocrine markers, one must be aware of pitfalls when assessing lesions with focal/diffuse synaptophysin immunoreactivity. Several non-neuroendocrine tumors may express this marker, so confirmation with additional stains = YES. An example:

Hello, PathTwitter! I have not been posting going here recently because of new work responsibilities last year, but this year one of the goals is to get back to doing things I actually like doing, such as learning from everyone here. Hope we have a good year ahead! 😊

Hello, first post in quite a while! Anyone also attending the 1st international congress of the Korean Society of Pathologists? 😊 I am quite shy in person ahaha but would try my best to say hi if some of you are also here!

Hello everyone! To pathologists here, what is the best whole slide image viewer (like Aperio ImageScope) for Mac? It seems we can only install ImageScope on Windows, and we are looking for an equivalent. Thank you! 😊
