Primary large B-cell lymphoma of the CNS: Cyclin-D1 highlights endothelial cells in brain tissue, however its pattern of expression could be misinterpreted as positivity in neoplastic cells. Comparison to MUM1 & PAX5 is helpful to avoid this pitfall #hemepath #lymsm #PathX

The most picturesque/textbook example of AITL you will see in 2024…
What the WHO 5th now refers to as “Nodal T follicular helper cell lymphoma, angioimmunoblastic type”
