'''Description''': On the right side of the slide can we see stratified squamous non-keratinizing epithelium. On the left side we can see stratified squamous keratinizing epithelium. On the top can we also see stratified squamous keratinizing epithelium, however the keratin here is very thin. On the bottom of a slide can skeletal muscle be seen.

In the middle of the slide can “pearls” of keratin be seen. On the top of the slide can a small piece of tissue be seen, and right underneath that piece is the mucosa eroded away. Tumor cells can be seen infiltrating the skeletal muscle.

'''Diagnosis''': Well-differentiated squamous cell carcinoma[[File:Squamous carcinoma of lower lip comparison.png|thumb|Comparison between the healthy keratinizing epithelium and the tumor cells. Among the tumor cells can we see pleomorphism (anisonucleosis, anisocytosis, anisochromasia), mitosis and prominent nuclei.]]'''Causes''':
