Hyperkeratotic?

SKIN LESION, LEFT EAR LOBE, EXCISION:
- SEBORRHEIC KERATOSIS (HYPERKERATOTIC TYPE).
- SOLAR ELASTOSIS.
- NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY.

Micro

The sections show skin with elongated rete ridges that focally curve toward the centre of the lesion, acanthosis, hyperkeratosis in vertical columns, and focally dilated blood vessels at the dermal-epidermal junction. No appreciable basilar nuclear enlargemnt is present. No definite koilocytic change is apparent.

No parakeratosis is identified. Marked solar elastosis is present. No melanocytic nests are apparent. Mitotic activity is not apparent.
