❌ Mucoepidermoid Carcinoma:
• Warthin-like variant can mimic this tumor but typically shows infiltrative borders and mucous cells.
• Features a mixture of epidermoid, intermediate, and mucinous cells rather than pure oncocytic bilayering.
• Characteristically harbors a CRTC1::MAML2 fusion, which is absent in true Warthin tumor.

[The Joint Pathology Center (JPC) @TheJPCNCR]

1. Mucoepidermoid carcinoma, low grade, Warthin tumor-like variant (scanned). Predominantly cystic parotid gland neoplasm with a dense lymphoplasmacytic tumor associated lymphoid proliferation (TALP). A MAML2 gene rearrangement is present, confirming the diagnosis. #PathTwitter

What do you see #medtwitter? And which category of central nervous system diseases would you most associate this finding with?

Do we grade thyroid cancer? Yes.

Per 2022 5th WHO:
If you have a histologically differentiated tumor
- Papillary carcinoma
- Follicular carcinoma
- Oncocytic carcinoma
with tumor necrosis (punctate to extensive, excluding FNA changes) or ≥5 mitoses per 2 mm², then you can call it high-grade differentiated thyroid carcinoma.
