Polyps

A general descriptive term used with reference to any mass of tissue that bulges or projects outward or upward from the normal surface level, thereby being macroscopically visible as a hemispheroidal, spheroidal, or irregular moundlike structure growing from a relatively broad base or a slender stalk. Classically applied to a growth on the mucous membrane of the nose, the term is now applied to such protrusions from any mucous membrane.
