Glad to have attended the 1st Oncology Pathology Forum, hosted by the Royal College of Pathologists of Thailand and the Thai Society of Clinical Oncology, earlier last month and congrats to my colleague, Dr. Pannawich, on his talk about bridging the gap between both specialties!

A must for pathology residents! Learned a lot about the basic principles of genomic assays and interpretation of results.

Congrats to everyone who matched this season!
While I unfortunately did not match, I’m staying hopeful and focused on the next steps. Any advice or recommendations would be greatly appreciated.

If you have what appears to be a large gastric hyperplastic polyp, or if you know several polyps are present in the stomach, you can topline your diagnosis as:
Hyperplastic/hamartomatous polyps with mild acute inflammation and reactive features
Add a comment about the possibility of gastric juvenile polyposis syndrome.
These polyps show lobular growth, a flat surface, and dilated glands.
SMAD4 IHC may be helpful in some cases (loss of SMAD4).

NIFTP or not NIFTP?
Round, well-demarcated lesion with nuclear changes resembling NIFTP (pic 1).
Penultimate and tip sections show irregularities in the external surface (pic 2-3).
Using an orange as analogy (pic 4), such irregularities are common at the tips.
If these changes are confined to those areas, call it NIFTP.

Workup of high-grade B-cell lymphoma/diffuse large B-cell lymphoma
- Establish cell of origin: Hans algorithm
- Assess for double-expressor lymphoma (DEL): MYC and BCL2 IHC
- Assess for double-hit lymphoma (DHL): FISH for MYC, BCL2, and BCL6

✔️prostatitis is a clinical Dx, not a🔬one
✔️if you have to add "focal", the inflammation is likely not needed to report
✔️if the inflammation isn't within a target/high PIRADS lesion, it may not be important to report

More from arppress.org/books/book/68:
Hyalinizing trabecular tumor is characterized by fusions of the GLIS genes (PAX8::GLIS1 and PAX8::GLIS3), and almost all have benign behavior. This tumor demonstrates a peculiar membranous staining pattern for ki-67 (MIB-1 monoclonal antibody) at room temperature; membranous staining is often absent using fully automated stains.

ALT HYALINIZING TRABECULAR TUMOR A main distinguishing feature is extensive intracellular and extracellular hyalinization. The cells are arranged in compact clusters reminiscent of the “Zellballen” of paraganglioma.
ALT HYALINIZING TRABECULAR TUMOR The cell membrane of the tumor cells stains with the proliferating marker MIB-1 (Ki-67). This peculiar phenomenon, which is probably of artifactual nature, is seen with some antibody clones but not with others.
Sebaceous carcinoma
- Commonly occurs around eyelids
- Atypical basaloid cells + variable sebaceous differentiation (multivacuolated cytoplasmic clearing)
- Oil Red O highlights lipid vacuoles
- IHC: + AR, adipophilin, AE1/3, EMA
