Understanding Your Pathology Report: Colon Polyps (Sessile or Traditional Serrated Adenomas) Adenomas have several different growth patterns that can be seen under the microscope by the pathologist. There are 2 major growth patterns: tubular and villous. Because many adenomas have a mixture of both growth patterns, some polyps may be called tubulovillous adenomas.Most adenomas that are small (less than ½ inch) have a tubular growth pattern. Larger adenomas may have a villous growth pattern.Larger adenomas more often have cancers developing in them.Adenomas with a villous growth pattern are also more likely to have cancers develop in them. polyp is a projection (growth) of tissue from the inner lining of the colon into the lumen (hollow center) of the colon. Different types of polyps look different under the microscope. Polyps are benign (non-cancerous) growths, but cancer can start in some types of polyps.

What is Nasal Papilloma? These growths are basically warts in the nose, and are often caused by viruses which lead to the development of warts, such as the human papilloma virus. The growth is hard, with a wrinkled and rough appearance, unlike a polyp, which is smooth. It can be located anywhere in the nose, and some people experience the development of multiple growths in their noses. Classically, a nasal papilloma blocks the nose, impeding breathing or sense of smell. People may also experience discomfort as the growth develops, and the growths can bleed. A rare type of growth known as an inverted or inverting nasal papilloma has growth which extends into the underlying tissues of the nose.
