Papilloma A papilloma (plural papillomas or papillomata) (papillo- + -oma) is a benign epithelial tumor growing exophytically (outwardly projecting) in nipple-like and often finger-like fronds.In this context papilla refers to the projection created by the tumor, not a tumor on an already existing papilla (such as the nipple).When used without context, it frequently refers to infections (squamous cell papilloma) caused by human papillomavirus (HPV), such as warts.Human papillomavirus infection is a major cause of cervical cancer, although most HPV infections do not cause cancer.There are, however, a number of other conditions that cause papilloma, as well as many cases in which there is no known cause.n this context papilla refers to the projection created by the tumor, not a tumor on an already existing papilla (such as the nipple). When used without context, it frequently refers to infections (squamous cell papilloma) caused by human papillomavirus (HPV), such as warts.

- Osteochondromas or osteocartilaginous exostoses are the most common benign tumors of the bones.[1] The tumors take the form of cartilage-capped bony projections or outgrowth on the surface of bones (exostoses).[2] It is characterized as a type of overgrowth that can occur in any bone where cartilage forms bone.

Hyperplasia Hyperplasia is considered to be a physiological (normal) response to a specific stimulus, and the cells of a hyperplastic growth remain subject to normal regulatory control mechanisms.May 2015). Hyperplasia (from ancient Greek ὑπέρ huper, over + πλάσις plasis, formation), or hypergenesis, is an increase in the amount of organic tissue that results from cell proliferation. It may lead to the gross enlargement of an organ and the term is sometimes confused with benign neoplasia or benign tumor.

Clinical Cases Osteophytosis Osteophytosis. Osteophytes, more commonly known as bone spurs, are outgrowths of bone tissue that form around damaged joints. This bone growth is thought to be a compensatory response to bone and ligament damage, and is meant to restrict movement of the joint to protect from further damage.steophytes, more commonly known as bone spurs, are outgrowths of bone tissue that form around damaged joints.

INVERTED PAPILLOMA OF NOSE & PARANASAL SINUSES: Inverted Papilloma is a benign neoplasm originating from the Schneiderian membrane of the nose and paranasal sinus cavities. It has varied clinical and histological features involving the lateral nasal wall, septum, ethmoids, maxillary and sphenoid sinuses and at times involves the skull base.

- Exostosis. a benign bony or bony-cartilaginous growth on the surface of a bone in the form of a linear or round mass. Exostoses develop mainly in males during childhood and adolescence, on the femur, tibia, humerus, and other bones. They cease to enlarge when bone growth ends.

Breast Apocrine Metaplasia Apocrine metaplasia is sometimes described as a ‘benign epithelial alteration’ of breast tissue, which means that epithelial cells are undergoing an unexpected change. The word apocrine means something to do with sweat, but only a resemblance. It’s not actually sweat gland related.pocrine metaplasia is a ‘ non-proliferative ‘ breast lesion, and is usually associated with breast fibrocystic disease. The term “proliferative” would mean that cells are growing and growing, and in a somewhat unpredictable way. Proliferative cells growth is therefore usually associated with carcinoma.

An overview of Focal Intestinal Metaplasia Focal intestinal metaplasia is the potentially reversible change from a fully differentiated stomach cell type to an intestinal cell type. It is associated with significantly increased risk of cancer.. Proper diagnosis and treatment can reduce the risk of gastric cancer.ntestinal metaplasia is also a common in Barrett esophagus. It this condition it is the esophageal squamous epithelial cells that undergo metaplasia. Approximately, 60% of esophageal cancers diagnosed in the U.S. stem from focal intestinal metaplasia.

Hyperplasia Hyperplasia, or hypergenesis, is an increase in the amount of organic tissue that results from cell proliferation. It may lead to the gross enlargement of an organ and the term is sometimes confused with benign neoplasia or benign tumor. Hyperplasia is a common preneoplastic response to stimulus. Microscopically, cells resemble normal cells but are increased in numbers. Sometimes cells may also be increased in size. Hyperplasia is different from hypertrophy in that the adaptive cell change in hy
