For a pedunculated protrusion, which best describes its base vs peripheral material?

• A. The base is larger than the material
• B. The peripheral material is larger than its attachment site
• C. There is no relation to base size
• D. The attachment site is larger than the material

Answer: (B)

In a pedunculated protrusion, the growth is attached by a narrow stalk to the surface, with most of the mass projecting outward beyond that small attachment. The stalk (attachment site) is comparatively tiny, while the peripheral material—the body of the lesion—forms a larger, visible portion away from the attachment. That’s why the best description is that the peripheral material is larger than its attachment site. If the lesion were broad-based and flat, the attachment would be wide and not small, which is the opposite situation.
