This medium power view shows the wall of a nest of squamous carcinoma with central cystic degeneration. The cells mimick the formation of a normal epithelium. The left lower corner of the photograph shows stroma. The cells lack maturation. Nuclei are large and vary in size and shape.
Some nucleoli are visible.
Nuclei show an irregular distribution of chromatin with clumping and clearing. Keratinization is not seen.
