A squamous cell is a type of epithelial cell, found in many different areas of the carcase. Although many people think epithelial cells as "skin" cells, they can actually be found cover many layers of the human body-not just without.
Squamous cells are flat, in contrast to the square (cuboidal) or rectangular (single column), epithelial cells are found in many parts of the body. You can find squamous cells in the mouth, lips, and on the cervix, as well as in in the middle layer of the skin. Squamous cells are epithelial cells pretty utilitarian, used to cover just about everywhere.
Most people only become familiar with the term squamous cell when they are diagnosed with a squamøs cell carcinoma-a kind of cancer. Squamøs cell carcinomas are the most common cancer in the oral cavity and is also commonly found in the cervix and the skin.
Women can also be familiar with the term squamous cell, because potentially precancerous, abnormal Pap smear results are diagnosed as squamous intraepithelial lesions. In this case, the squamous cells in the cervix has taken an abnormal morphology, or a figure, but they have not necessarily becoming malignant. Actually heal lower grade squamous intraepithelial lesions or cervical dysplasias often even without intervention.
