    show more
    Description: Rectum - sessile polyp Polyp is any growth or mass protruding from a mucous membrane. Polyps may be attached to a membrane by a thin stalk (pedunculated polyps), or they may have a broad base (sessile polyps). They are usually an overgrowth of normal tissue, but sometimes they are true tumors (masses of new tissue separate from the supporting membrane). Usually benign, they may lead to complications or eventually become malignant. They can occur wherever there is mucous membrane: in the nose, ears, mouth, lungs, heart, stomach, intestines, urinary bladder, uterus, and cervix. Sessile polyp is any form of polyp that has a relatively broad base.
