A solar lentigo (plural, solar lentigines), also referred to as a sun-induced freckle or senile lentigo, may be a dark (hyperpigmented) lesion caused by natural or artificial ultraviolet (UV) light. Solar lentigines could also be single or multiple. This sort of lentigo is different from an easy lentigo (lentigo simplex) because it's caused by exposure to UV light. Solar lentigines are benign, but they are doing indicate excessive sun exposure, a risk factor for the event of carcinoma.
Who's at risk?
Solar lentigines most ordinarily occur in older adults, particularly those that sunburn easily and fail to tan, but they'll also occur in children.
Signs and Symptoms
Solar lentigines typically appear on areas exposed to natural or artificial UV light. they seem as well-defined, brown to black, flat spots. In people that are treated with a sort of UV light therapy called PUVA, solar lentigines may occur in areas of the skin not exposed to UV light.
To prevent solar lentigines, avoid exposure to sunlight in midday (10 AM to three PM), wear sun-protective clothing (tightly woven clothes and hats), and apply sunscreen (SPF 30 UVA and UVB block).
When to hunt medical aid
Solar lentigines don't require medical therapy, but see a physician for evaluation if they become cosmetically bothersome or if you're uncertain about any pigmented spot on your body.
Treatments Your Physician May Prescribe
If solar lentigines are cosmetically bothersome, your physician may:
Ø Freeze the world lightly with nitrogen.
Ø Prescribe a bleaching cream (hydroquinone), but this is often often not successful.
