			===Micro===
			The sections show an epithelial tumour with squamoid features, mild pleomorphism and whirling, that underlies a benign epidermis. Degenerative changes are present. Rare mitotic figures are seen.

			PAS and PASD staining shows PAS-positive diastase-resistant droplets. The tumour is CAM5.2 POSITIVE, S-100 NEGATIVE and SMA NEGATIVE.
