This means the hyperplasia of melanocytes is restricted to the cell layer directly above the basement membrane of the epidermis where melanocytes normally reside. This is in contrast to the 'nests' of multi-layer melanocytes found in moles (melanocytic nevi). Because of this characteristic feature the word "Lentiginous", an adjective, is used to describe other skin lesion that similarly proliferate linearly within the basal cell layer.

Lentigo differs from freckles (ephelis) on the issue of proliferation of melanocytes. Freckles have a relatively normal number of melanocytes but increased amount of melanin.
