Adenomkarzinom und villöses Adenom des Colon ascendens

Adenomkarzinom und villöses Adenom des Colon ascendensThis ascending colon tumor shows two distinct components,

a non-invasive villous adenoma on the right of the image, giving rise to

an invasive mucinous carcinoma on the left.

The latter tumor has interrupted the ribbon-like contour of the muscularis propria. Despite the transmural invasion, all 19 lymph nodes were negative for tumor.Source: Ed Uthman, MD
