Definition

The lamina propria is composed of areolar connective tissue, contains blood vessels, nerves, and, in some regions, glands. It lies just under the epithelium of a mucous membrane.

Once a tumor has broken through the basement membrane into the lamina propria, it can spread by way of the lymphatics and the blood vessels to the other parts of the body.
