| Clinically,
these lesions appear as an elevated, thickened area of epithelium which
may have an ulcerated or friable surface (#21858).
Histopathologically (#21859), the lesion is characterized by
invasion of malignant squamous cells into the dermal tissue. These cells are large and stain a light pink in color with
marked nuclear dysplastic changes. They
often tend to show abnormal deep keratinization or dyskeratosis and
sometimes form nests with whorls or pearls of keratinized material.
