Images 1,2 and 6, to me are poroid and look like poroma. The infiltrative pattern in images 7 and 8 is worrisome. I need a scanning view of the lesion !!!!

In image 1 I see a large epithelial lobule with smooth contour and thick basement membrane. Images 7 and 8 show what I think are pseudoinfiltrative features. In images 9, 10 and 11 there are dilated capillaries within dermal papillae and maybe other features suggestive of common warts. I think this is desmoplastic trichilemmoma. As a second possibility, depending on a complete examination of the lesion, an old verruca vulgaris with trichilemmoma-like areas.

I thought of desmoplastic seborrheic keratosis.

I agree With Dr Abdel Halim about the need of an ovaerall view. These close-up snapshots show a squamous lesion, without definite evidence of malignancy, but I can't go any further. This may well be a tricholemmoma, but I am far from convinced.

Can't see significant cellular atypia. Given the anatomic location traumatised (focally desmoplastic) tricholemmoma would be my favoured diagnosis. CD34 and PAS (highlights BM) should be helpful.

Thank you all for your comments on a bank holiday here in the UK. The final diagnosis is desmoplastic trichilemmoma and as Richard says there is no significant atypia.
