Histology slide of a solar lentigo. Differently from the melanotic nevi and the verrucous nevi on the skin, age spots change in color and in shape with time. Wang-Michelitsch and Michelitsch propose a hypothesis inspired by their misrepair-accumulation aging theory [12] for the development of age spots. [13]
A lentigo (/ l ɛ n ˈ t aɪ ɡ oʊ /) (plural lentigines, / l ɛ n ˈ t ɪ dʒ ɪ n iː z /) is a small pigmented spot on the skin with a clearly defined edge, surrounded by normal-appearing skin. It is a harmless (benign) hyperplasia of melanocytes which is linear in its spread.
Lentigo maligna is where melanocyte cells have become malignant and grow continuously along the stratum basale of the skin, [1] but have not invaded below the epidermis. [2] Lentigo maligna is not the same as lentigo maligna melanoma, as detailed below. It typically progresses very slowly and can remain in a non-invasive form for years.
Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...
Polarized light allows for visualization of deeper skin structures, while non-polarized light provide information about the superficial skin. Most modern dermatoscopes allow the physician to toggle between the two modes, which provide complementary information. Others may also allow the doctor to have different zoom levels and color overlay.
Ink spot lentigo is a cutaneous condition characterized by skin lesions commonly occurring on the shoulders. [1] These lesions often cause alarm but are benign. They are an indication of excessive sun exposure so although ink spot lentigo is not premalignant, people with several of them maybe at increased risk of skin cancer due to UV damage.

These are spotted areas created by accumulation in the skin due to sun exposure. Due to a high irregularity any distinction from randomness defines lentiginosis. Although lentigines are benign, they be the signal of an underlying problem such as progressive cardiomyopathic lentiginosis , which can cause retardation in children.
