The sections show hair bearing skin. The squamous epithelium has full thickness changes including an increased nuclear-cytoplasmic ratio, loss of polarity, and nuclear hyperchromasia. Mitoses are seen in the upper third of the epithelium. Nucleoli are not apparent. No atypical cells are seen in the dermis. Parakeratosis overlies the abnormal keratinocytes. Solar elastosis is present. No melanocytic nests are identified. | The sections show hair bearing skin.

The sections show hair bearing skin. The squamous epithelium has full thickness changes including increased nuclear-cytoplasmic ratio, nuclear enlargement, loss of polarity, and nuclear hyperchromasia. Mitotic figures are easily identified. | |||
No atypical cells are seen in the dermis; however, the epidermis is thickened. The dermal epidermal interface has a smooth contour. No paradoxical differentiation is identified. Inflammation at the dermal epidermal junction is minimal. Parakeratosis overlies the normal keratinocytes. The lesion is completely excised in the plane of section. Dermal scarring is present. | |||
