I checked the images and they are fine at my end. There is no evidence of ductal differentiation and so the lesion is not hidroacanthoma simplex. In melanoacanthoma, there should be much more melanin pigment. The lesion is a clonal seborrheic keratosis.

I too think it is a clonal seb k. I cannot appreciate any ductal differentiation in these photomicrographs to suggest intraepidermal poroma (hidroacanthoma).

Looks like a clonal pattern seb k but with increased numbers of uniform melanocytes so I wondered about melanoacanthoma.

To me the cells are slightly poroid and I thought of hidroacanthoma simplex, especially with the thin proliferating strands,
