Final answer:
The subtypes of neoplastic polyps are tubular adenomas, villous adenomas, and tubulovillous adenomas. These subtypes are based on their histological appearance and the proportion of glandular and villous components.
Step-by-step explanation:
The subtypes of neoplastic polyps are:
- Tubular adenomas
- Villous adenomas
- Tubulovillous adenomas
Neoplastic polyps are abnormal growths in the colon or rectum that have the potential to become cancerous if left untreated. These subtypes are differentiated based on their histological appearance and the proportion of glandular and villous components. Tubular adenomas consist mostly of tubular glands, while villous adenomas have a predominantly villous structure. Tubulovillous adenomas have a combination of both tubular and villous features.
