What is a Lentigo?
There are several skin lesions that are very common and benign (non‐cancerous). These conditions
include moles, freckles, skin tags, benign lentigines, and seborrheic keratoses. A lentigo (plural:
lentigines) is a benign spot on the skin that is darker (usually brown) than the surrounding skin. A
lentigo is one of the most common growths that occur on the skin. Lentigo is often referred to as
liver spots or age spots. Lentigo are most frequently seen in adults over thirty, and they occur most
commonly on sun exposed skin, face, back of hands, arms, chest and lower legs. Lentigines are more
common among whites, especially those with fair skin. Lentigines are benign, but they do indicate
excessive sun exposure, a risk factor for the development of skin cancer.
