(dis-PLAY-zhuh) A term used to describe the presence of abnormal cells within a tissue or organ. Dysplasia is not cancer, but it may sometimes become cancer. Dysplasia can be mild, moderate, or severe, depending on how abnormal the cells look under a microscope and how much of the tissue or organ is affected. Enlarge.

Ectodermal dysplasia is a hereditary disorder associated with abnormal development of embryonic ectodermally-derived organs including teeth, nails, hair and sweat glands. Hypodontia of the primary and permanent dentition is the most com-mon oral finding.

A severely dysplastic nevus is indistinguishable from early melanoma. Very often these lesions show considerable irregularity of edge and irregularly irregular colour. The differentiation between a moderate and severely dysplastic nevus is one of degree. Mildly dysplastic nevi can be observed.

Low-grade dysplasia means that some of the cells look abnormal when seen under the microscope. These cells may look a lot like cancer cells in some ways, but unlike cancer, they do not have the ability to spread all over your body.

Dysplastic pulmonary stenosis is a less common variety with obstruction caused by myxomatous thickening of three separate but poor mobile leaflets without commissural fusion. It is associated with Noonan syndrome and hypertrophic cardiomyopathy.

Dysplasia, a premalignant condition, refers to abnormal epithelial growth characterized by a spectrum of cytologic, maturational and architectural changes. Carcinoma in situ means abnormal changes are seen in the entire thickness of epithelium, extending from basal cell layer to surface.

The word “dysplasia” means “abnormality of development”. Hip dysplasia is a canine genetic condition in which there is a tendency towards development of hip laxity early in life. Hip dysplasia is not congenital because affected dogs are born with morphologically normal hips.

What is cervical dysplasia? Cervical dysplasia is when there are abnormal, or precancerous, cells in and around a woman's cervix. The vagina opens up into the cervix, which is the lower part of the uterus. Cervical dysplasia is detected by a pap test (pap smear).

Oral epithelial dysplasia is a term used to describe harmful changes in the cells that make up the lining (epithelium) of the mouth. The changes occur because of damage to the cells' DNA by cancer causing chemicals (carcinogens).

Hip dysplasia is when the hip joints don't fit together properly and become unstable. Hip dysplasia causes pain, swelling, stiffness and eventually arthritis. Dogs with hip dysplasia usually begin showing symptoms while they are growing (at around 5-6 months of age).

A: Dysplasia is a microscopic diagnosis made after looking at a piece of the oral tissue (biopsy) under a microscope. It means that there are premalignant changes that may progress to malignancy but there is no cancer.

Low-grade neoplasia (CIN 1) refers to dysplasia that involves about one-third of the thickness of the epithelium. CIN 2 refers to abnormal changes in about one-third to two-thirds of the epithelial layer. CIN 3 (the most severe form) describes a condition that affects more than two-thirds of the epithelium.

Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body's normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.

An oral precancerous lesion, also called dysplasia, is a growth that contains abnormal cells confined to the lining of the oral cavity, or mouth. This lining is called the mucosa. It covers the inside of the cheeks, the inside of the lips, the gums, the tongue, and the roof and floor of the mouth.

Vulvar intraepithelial neoplasia (VIN) is a precancerous change in your vulva. VIN is not cancer. But if it's not treated it can turn into cancer. Intraepithelial means that the precancer cells are only in the surface of the vulvar skin. Another name for VIN is dysplasia.

Hip dysplasia is a canine genetic condition in which there is a tendency towards development of hip laxity early in life. Hip dysplasia is not congenital because affected dogs are born with morphologically normal hips.

neoplastic, it appears that low-grade dysplasia in Barrett is equivalent to forms of mild dysplasia in the stomach, while high-grade dysplasia equals moderate and severe dysplasia. The moderate or intermediate grade is not classically used for Barrett's esophagus.
