case_images: On physical examination, a 6.0 cm exophytic mass is found on the left occipital scalp (Figure 1).
case_images: Verrucous Carcinoma. Marked digitated acanthosis of is associated with bulbous aggregates of squamous epithelium, producing a pushing border. Cytologic atypia was minimal. A focus of SCAP is present at the lower left 20x.

case_images: On histopathologic examination, a large verrucous proliferation comprised of stratified squamous epithelium with slight atypia is seen (Figure 2).
case_images: SCAP. Columnar epithelial cells with decapitation secretion line a papillated structure. A myoepithelial cell layer was present. The stroma contains numerous plasma cells 20x.
