Squamous epithelial cells are flat cells found in several body parts, including the mouth, lips, and cervix. They can also be visible in the middle skin layers.
Squamous cell carcinoma is a form of cancer affecting the squamous layers of the epithelium. It is the most prevalent type of oral cavity cancer. It is also widespread in the skin and cervix.
The term mucosa refers to the moist inner lining of body cavities and some organs, e.g. lungs, stomach, intestines, oesophagus, nose, mouth, etc. When the top layer is composed of squamous cells, it is called squamous mucosa. Under a microscope, flat squamous cells resemble fish scales. Squamous mucosa covers the majority of the oesophagus. The oesophagus is a tubular structure that joins the mouth to the stomach. The gastro-oesophageal junction, also known as the GEJ, is where the oesophagus and stomach merge.
