Non-neoplastic esophageal biopsy approach

Low power first.
🟣 Parakeratosis → Candida 🍄
🔵 Hyperplasia → Glycogenic acanthosis
🔥 Ulcer → Reflux
🧬 Granular layer → Epidermoid metaplasia

Distal rectal polyp - HPV-associated glandular neoplasms are rare and mimic tubulovillous adenomas. The mucin is peculiar and apical apoptotic bodies can be plentiful (arrow).

Voltaggio L, et al. Mod Pathol. 2020 May;33(5):944-952. PMID: 31857682.

Another spectacular EBV-associated gastric carcinoma (gastric carcinoma with lymphoid stroma). This example has overt gland formation and more sheet-like areas.

1/2. Sessile serrated lesion (SSL) with benign colonisation of lymphoglandular complexes (gut-associated lymphoid tissue / GALT) #pathtwitter @Pathoutlines @RaulSGonzalezMD

This week, I learned not only that gangliocytic paragangliomas were reclassified by the WHO as composite gangliocytoma/neuroma and neuroendocrine tumor (CoGNET) - thank you Rhonda Yantiss - but also that they can express CD117/KIT to result in wrong diagnoses on small biopsies.

[Elizabeth Montgomery, MD @LizMontgomeryMD]

Inflammatory fibroid polyp is a neoplasm with PDGFRA mutations. Small bowel examples tend to present with intussusception. Mitoses (arrow) are infrequent. Gastric examples are usually antral and some have giant cells. The background eosinophils are typical. #UmiamiPath

Gastric fundic gland polyps and a foveolar adenoma from a patient with gastric adenocarcinoma proximal polyposis syndrome (GAPPS), a variant of familial adenomatous polyposis. Because the APC gene is large, the mutation was not detected until 2016. #umiamipath

This is a striking example of portal hypertensive colopathy in a patient with cirrhosis. #umiamipath

[Elizabeth Montgomery, MD @LizMontgomeryMD]

Colonic ganglioneuromas are often a component of the polyposis in patients with the PTEN hamartoma (Cowden) syndrome. These patients have skin lesions (facial trichilemmoma, acral keratoses, papillomatous papules) can develop malignancies (esp. of breast, thyroid). #umiamipath

How well do you know your variants of colon cancer? 🤔🔬 The WHO 🌍 has its list of recognized variants, but do you know which ones are important, which are no longer recognized, and which have been discarded? 🚫💡 Dive into the details and stay informed! https://t.co/8EUSPnspQt

Colonic polyp with an inflammatory process related to defective macrophage response to bacterial infection, mostly coliform bacteria. Classic Michaelis-Gutman bodies. PMID: 32301754 @UMiamiPathology
