Lentigohttps://en.wikipedia.org/wiki/Lentigo
Lentigo is a small pigmented spot on the skin with a clearly defined edge. Lentigos are disorders on the skin associated with aging and exposure to ultraviolet radiation from the sun. They are located in areas most often exposed to the sun, particularly the hands, face, shoulders, arms and forehead, and the scalp if bald.

In the majority of cases, lentigo pose no threat and require no treatment, though they occasionally have been known to obscure the detection of skin cancer. However, despite being a non-life threatning benign condition, lentigos are sometimes considered unsightly and removed.

All 12 patients were treated in 5 to 12 sessions with low-fluence QS Nd:YAG laser, pulse duration of 5∼10 nsec, spot size of 8 mm, and fluence of 0.8∼2.0 J/cm2. Repetitive low fluence 1064 Nd:YAG laser treatment may be an effective and safe optional modality for senile lentigo.
