View source for 30. Lymphomatous polyposis of small and large intestine

[[File:Mantle cell lymphoma intestine prep.jpg|thumb|Mantle cell lymphoma intestine prep|587x587px]]'''Organ''': Large intestine

'''Description''':

The mucus membrane of the intestine is filled with polyps.

'''Diagnosis''': Lymphomatous polyposis (due to mantle cell lymphoma)

'''Causes''':

* Translocation of cyclin D1 gene into IgH gene – t(11;14)

'''Theory''':

Like the case was for the Burkitt lymphoma – there’s no way to diagnose these polyps as mantle cell lymphoma without histology. These polyps could also be due to:

* Familiar adenomatous polyposis
* Ulcerative colitis
* Hamartomatous polyps
