Other names: Simple lentigo[1]

Lentigo simplex is a dark spot, typically 3mm to 15mm, and round to oval, with an irregular or regular edge.[2] It does not itch or hurt and characteristaically has a uniform color.[2]

It is the most common form of lentigo.[3]: 29  A single lesion or multiple lesions (lentigines) may be present at birth or more commonly first develop in early childhood. Lentigo simplex is not induced by sun exposure, and it is not associated with any medical diseases or conditions. It is also referred to as simple lentigo and juvenile lentigo.[citation needed] This condition also affects cats, those with orange coloration most often, and can appear on the nose, lips, and eyes as the cat ages.[4]
