Occult Pigmentation

An elderly man presented with a skin coloured lesion on his ear. I shaved it prior to curetting it but was surprised by what I found in the base. This did not appear to be hemorrhage. I have provided you with a dermatoscopic image of the undersurface of the shaved lesion. What is going on here? 

This was the pathology of the top shave

This is the histology of the second shave of the pigmented area.
