Squamous epithelium is one of several types of epithelia.

In anatomy, squamous epithelium (from Latin squama, "scale") is an epithelium characterised by its most superficial layer consisting of flat, scale-like cells called squamous cell. Epithelium may possess only one layer of these cells, in which case it is referred to as simple squamous epithelium; or it may possess multiple layers, referred to then as stratified squamous epithelium. Both types perform differing functions, ranging from nutrient exchange to protection.

[edit] Cancers of the squamous cell epithelium

These include squamous cell carcinoma, basal cell carcinoma, and other adnexal tumors.
