Here's an odd 🐦
Microscopic colitis pattern, but you find rows of giant cells and macrophages have accumulated in the upper mucosal reaches.
Normal colonoscopy, no medication, usual reason to investigate.
What's going on? #GIpath
Biopsies of a duodenal D1 polyp. More pictures in next tweet.
Would be interested in how people would report this?
Perhaps the ultimate label doesn't matter that much as I think it needs removal.

@miss_me1986 Low power view of diaphragm disease highlights the difference in height between the diaphragms and the adjacent normal plicae circularis 🔬
Submucosal infiltration in ESD specimens often provokes extensive fraying of the muscularis mucosae.
Measure infiltration depth from deepest fibre MM, true volume of disease often larger than raw depth indicates.
Here 620 micron, T1b SM2, 15% risk LNs

#PathPitfall, Frozens Edition:
We often freeze nodules on the liver looking for mets. When we see a proliferation of glands in the liver, a knee-jerk response is: metastatic adenoca!
BUT don't forget our friend bile duct hamartoma- common, often incidentally found, and benign!
Another entry for our competition in celebration of @RCPath National #PathologyWeek from Sarah in Cellular Pathology, with the proof that pathology truly is at the #HeartOfHealthcare 💜🔬
These 'thickened gastric folds' in a 50yo man showed 4 different diagnoses, all of them benign 😀
🕐 Superficial active gastritis (see those neutrophils! HP present, not shown
🕑 Intestinal metaplasia, non dysplastic (probably related to atrophy)

Hey #Pathologists, what do you think of this enlarged inguinal lymph node from 62 yo male with CLL? Part of node shows SLL/CLL but part is necrotic and edematous. What’s going on?
An unusual colorectal perineurioma with meningothelial-like whorls. Our Intestines Fascicle covers these but the treat is the polyps section by Dale Snover, who "invented" the sessile serrated adenoma, now renamed as sessile serrated lesion by the WHO. https://t.co/Uu8QV9Petx
h. pylori vs h. heilmannii:
HP: common, gram neg, 3.5 um, curved rod. 80% of infected pts asymptomatic.
HH: rare, gram neg, 5-9 um, tight spirals. Human infection is zoonotic, from household pets or farm animals. Antibiotic therapy similar to HP. #gipath#gibugs#pathology
Case of the week (contributed by Dr. Chirag Patel):
The patient is a 45 year old HIV+ Male with hematemesis and weight loss. Endoscopy reveals maroon-red distal esophageal plaques and nodules.
Microscopic examination reveals the following. Diagnosis?
This inflammatory fibroid polyp of the colon either induced low-grade dysplasia in the overlying epithelium, or arose within a pre-existing focus of dysplasia. Doesn't happen often! https://t.co/evENvb1oWD #pathology#gipath
