http://ncicb.nci.nih.gov/xml/owl/EVS/Thesaurus.owl#C3159

Small circumscribed melanoses resembling, but differing histologically from, freckles. The concept includes senile lentigo ('liver spots') and nevoid lentigo (nevus spilus, lentigo simplex) and may also occur in association with multiple congenital defects or congenital syndromes (e.g., Peutz-Jeghers syndrome).

C3159

A flat, benign, pigmented spot on the skin caused by excessive deposition of melanin from an increased number of melanocytes in the cell layer directly above the basement membrane of the epidermis. Formation is usually related to sun exposure during youth, and the lesions do not typically progress to malignancy.
