Lentigines (plural for lentigo) are circumscribed hypermelanoses associated with an increased number of epidermal melanocytes.

Clinically, a lentigine is a uniform brown or black macule, varying from 1-10 mm in diameter.

Ginger cats often have multiple lentigines around the mucocutaneous junctions of the face (lips, nose and eyelids), referred collectively as lentigo simplex. The lesions often appear at one year of age and progressively increase in size and number, eventually coalescing[1].
