Most head and neck cancers are squamous cell carcinomas, meaning they begin in the flat, squamous cells that make up the thin, surface layer (called the epithelium) of the structures in the head and neck.

Instead of creating a flap in the cornea, the surgeon creates a flap only in the cornea's thin protective cover (epithelium).

About 85 percent to 90 percent of ovarian cancers develop in the epithelium, the thin layer of tissue that covers the ovaries. This form of ovarian cancer generally occurs in postmenopausal women. Germ cell tumors.

One of these layers of tissue is called the epithelium. It covers the inside of hollow organs and milk ducts in the breast. When cancer occurs in one of the cells of the epithelium, it is called an adenocarcinoma.

A recurrent corneal erosion is the recurrent breakdown of the outermost layer (epithelium) of the cornea.

This is a tumor that develops from the squamous cells which are flat, scalelike cells in the outer layer of the skin (the epithelium).

Both arise from epithelial tissue (see epithelium). They are rare in dark-skinned people; light-skinned, blue-eyed people who do not tan well but who have had significant exposure to the rays of the sun are at highest risk.

The lining of the airways and windpipe is made up of rectangular-shaped surface cells (columnar epithelium) and glands that produce mucus and other fluids. In healthy lungs, these cells divide in a controlled and orderly way.

A dermoid cyst is lined with epithelium, which contains tissues and cells normally present in skin layers, including hair follicles, sebaceous (skin oil), and sweat glands.

retinal detachment - separation of the retina from the epithelium layer and from blood supply. retinopathy - diabetic eye disease. retrolisthesis - posterior slippage of one vertebra onto another.

These cells can become covered by a type of skin cells called squamous epithelium. When this happens, the secretions build up in the plugged cells. They form a smooth, rounded bump on the cervix. The bump is called a nabothian cyst.
