Villous adenoma is a type of polyp that grows in the colon, anywhere else in the gastrointestinal tract, or occasionally other parts of the body. These polyps start out benign, but can become malignant. Villous adenoma has been demonstrated to contain malignant parts in up to one third of affected persons and invasive malignancy in another one third of removed samples. If the affected polyp is large it may be necessary to remove part of the colon.
Villous adenomas can cause severe diarrhea. Since Villous adenoma often create mucus, it can cause the infected perfson to get hypokalemia, which means they have a low level of potassium in the blood.
