@Caetano_Pathol @SumantaDas_7 So beautiful!

Peutz Jeghers polyp! Love how IHC pops out the "tree morphology"

Ever increasing spectrum of MUC4 positive lesions

@SumantaDas_7 Why does it look familiar 😛 Very nice case though✨

Adult male. Arm swelling. Frozen section. #PathX #PathTwitter #BSTPath

Metastases to Small Intestine - Colonize surface mucosa, creating the impression of a "precursor" - Asynchronous architecture and cytology - Patchy surface involvement - Predominantly intravascular distribution Uterine (endometrioid) carcinoma metastatic to small intestine (pic 2) Prostate cancer metastatic to small intestine (pics 3-4) Always check history if available Dr. Panarelli - 2025 Diagnostic Pathology Update #USCAP #PathX #PathTwitter

Hands down; an important bookmark! 2026 seems to be on fire!

If your new year resolution was to exercise, here’s a workout for the pathology brains!! Happy new year everyone!! ✨

New in #HumPathol: Colloid cysts of the third ventricle show consistent expression of PAX8 but lack other features of thyroid, müllerian or intestinal differentiation. sciencedirect.com/science/articl… #pathology #PathTwitter #PathX #neuropath

Adult male. Cerebellar SOL. #PathX #PathTwitter #NeuroPath

A wonderful tweetorial to cover the bases. #PathX #PathTwitter

Adult female. Ovarian mass. Scrape smears prepared during the frozen section. #CytoPath #GynPath #CytoHisto correlation

@ariabdullah1978 @AmarBasharMD Ask for history of any prior tumor or clinical conplaint. It looks a metastatic nodule. Melanoma or epithelioid mpnst. Would do a hmb45 , ini and h3k27me3

64 F, 5.5cm Rt. thyroid mass, Cytokeratin, PAX8, TTF1, P40, CD30, CD34, CD117, STAT6, S100, CD45, ERG, CD31, EMA, INSIM1, Desmin, GATA3, SALL4, and BRAF all are Negative, necrosis with high mitosis. What else do you request and how do you sign it out? #PathTwitter #PathX SET1:

Too good compilation. #Tweetorial.

Brain teaser!

@NadesanAkhil That’s a great question—and it comes up ALL the time. Usually—HepPar1-positivity in an adenocarcinoma is evidence of “small intestinal enterocyte” differentiation. People usually jump to equating it with “hepatoid adenocarcinoma” but it almost never is (1/2)

A reminder that cutaneous tumors can occur anywhere.
