Ink spot lentigo
Ink Spot Lentigo
Ink spot lentigo (pronunciation: /ˈɪŋk spɒt lɛnˈtaɪgoʊ/), also known as reticulated black solar lentigo, is a type of lentigo that is characterized by dark, ink-like spots on the skin.
Etymology
The term "lentigo" originates from the Latin word lentiginosus, which means "full of freckles". The term "ink spot" is used to describe the appearance of the spots, which are similar to ink stains.
Description
Ink spot lentigo typically appears as a flat, dark brown or black spot on the skin. The spots are usually irregular in shape and have a reticulated or net-like pattern. They are most commonly found on sun-exposed areas of the skin, such as the face, hands, and arms.
Causes
Ink spot lentigo is caused by an increase in the number of melanocytes, the cells that produce melanin, in the skin. This increase in melanocytes is often triggered by exposure to ultraviolet (UV) radiation from the sun or tanning beds.
