How long have we known about glomeruli? Today’s teaching point is offered in honor of Marcello Malpighi (1628-1694), the Italian anatomist who is credited with having published the world’s first accurate description of glomerular structure (Bologna, Italy 1666). We learn from those who teach us!

Metastases to Small Intestine
- Colonize surface mucosa, creating the impression of a "precursor"
- Asynchronous architecture and cytology
- Patchy surface involvement
- Predominantly intravascular distribution

The Epigenetic Engines of Cancer: Decoding the SWI/SNF Complex 🧬⚙️
From the brain (AT/RT) to the lung (SMARCA4-def) to the kidney (MRT). Different organs. Different ages. Same Molecular Culprit.
Why does the loss of one "Chromatin Remodeler" create the most aggressive, chemo-resistant tumors?
