I am not comfortable. Fourth image shows long dendrites extending high up in the spinous layer. Melan A shows very contiguous melanocyte proliferation. I think this is early ALM in situ.

Lentiginous melanocytic proliferation sparing suprapapillary plates, favoring acral lentiginous nevus.

Age is a slight concern. Based on pigment in the furrows likely to be benign! Dermoscopy is said to be very helpful in acral lesions and we are given no clinical features so cannot really report on what we have.

It has been recommended we examine the specimen perpendicular to the skin markings to show this useful feature. I am guessing most of the brown on MelanA is melanin but would be nice to see a red chromagen or pre-bleach.
