Histopathology Colon--Villous adenoma

Colon Tumor with Villus Adenoma

In this section, the speaker discusses a colon tumor with villus adenoma and its features.

Features of Villus Adenoma

• Villus adenomas have a shaggy or sessile pattern of growth.

• They have little linear papillary projections or villi instead of tubules, implying faster growth rates.

• Villus adenomas have a higher association with malignancy than tubular adenomas due to their faster growth rates and closer association with carcinoma.

Cancer Association Rates

• Villus adenomas will eventually turn into carcinomas unless removed.

• This particular colon tumor has not infiltrated into the submucosal tissues yet, but it has a 100% cancer association rate over time.

Overall, the speaker emphasizes the importance of removing villus adenomas to prevent them from turning into carcinomas.
