Villous Adenoma Histopathology - Madeformedical.com

Villous adenoma is a type of polyp found in the colon or rectum that can sometimes develop into colorectal cancer. Histologically, villous adenomas are characterized by finger-like projections called villi, which are covered with dysplastic (abnormal) glandular epithelium. The glandular structures within the villi often show varying degrees of dysplasia, with enlarged, hyperchromatic nuclei and increased mitotic activity. The tissue architecture can be disorganized, and cribriform (sieve-like) patterns might be present. It's important to closely examine villous adenomas as they can have varying degrees of dysplasia and might progress to malignancy if left untreated.
