@AMubeen_Path#cytology#cytopath Clue of Mesothelioma vs Adenoca. In effusions:
♦️Groupings of mesothelial cells have rounded borders and look like the petals of a drawn flower
♦️Groupings of Adenocarcinoma cells often lack rounded bulbous individual cell contour and have a community border
Oral epithelial dysplasia
WHO-2022: 3-tiered grading system
Defining dysplasia grade only in this manner oversimplifies the complexity of grading
Cytological atypia confined to the basal third may be sufficient for a diagnosis of severe dysplasia, depending on individual features present, particularly bulbous rete processes, budding and disorganization of basal cells, and marked pleomorphism

Not always easy to recognise #FlatEpithelialAtypia, but hope this composite image may help. On ⬅️ columnar cell change (elongated bland nuclei). On ➡️ FEA - smooth contour, >1 layer, low grade round nuclei (like LGDCIS), not perpendicular to basement membrane.

It reminds me of Kikuchi, but there are neutrophils and there is too much CD20...
Note the difference between "normal" germinal centers (BCL6+, high Ki67, CD23+) and the "pale areas", which are mostly B

Slow-growing lesion in the lung (3 cm, was present since 2021) 🫁
I don't see clear signs of invasive carcinoma (too cystic?)
What do you think about the term "lung adenoma with enteric morphology"?
