Duodenal vasculitis with fibrinoid necrosis. The patient has systemic ANCA+ microscopic polyangiitis with mononeuritis multiplex. This can lead to GI bleeding so the vasculitis can show up in a D2 biopsy as long as the gastroenterologist gets a decent bite of submucosa #GIpath

In addition to esophageal dysplasia with cardiac/pyloric differentiation, this patient has an esophageal granular cell tumor. innovativesciencepress.com Modern Pathology

Pancreatic cytology is peculiar; adequacy is evaluated according to context not cellularity! Here is a totally acellular aspirate from a pancreatic cyst in a perimenopausal woman that is perfectly diagnostic 👌🏽 #Gipath #Pathology #Cytology #PathX #PathTwitter

This case was a referral rather than a true consult. The diagnosis was suspicious for invasive carcinoma. Do you agree? I have a definite opinion and diagnosis instead. Let me know what you think and please elaborate :) IHC: CK, p63, and SMM. ER is negative. #breastpath #PathX

Just like the poll shows, this is a tricky case. Ultimately, CK5/6 and ER shows a DCIS (G2 in my opinion) 😃some of you just can´t be fooled (not that I was trying...)Dr. Luca Olaleke Folaranmi Fouad Boulos Raza Hoda MD Alexander Damron, MD Brian McMillen MD Liza Quintana, MD Tania Labiano #breastpath

Here's the bonus case addressing p63 pitfalls. This scenario has been discussed before and it is quite controversial with no hard evidence to support either viewpoint. I do know where I stand on the matter though. Images show H&E, p63 and CK5/6. What is your diagnosis?
