This is a difficult case(for me)

First images show a  hyperplastic verrucous lesion, with thick epidermal basal membrane that would define lichen sclerosis Et atrophicus hypertrophic variant.  Last imgs show an infiltrative squamous lesion that would define Verrucous Carcinoma. I think this is infiltrative because of abnormal absence of basal layer and desmoplastic reaction around it.

I agree we see lichen sclerosus, appart from that for me there is a transition of differentiated Pein to penile squamous cell carcinoma (usual type). Picture 7 shows the aforementioned transition.
