Dermatology - Solar Lentigo 
Solar Lentigo 
Localized melanocyte proliferation brought on by either acute or long-term UV exposure is the cause of solar lentigines. The onset typically occurs beyond the age of 40, with lighter-skinned people having a higher incidence.

One to three centimeter and up to five centimeter macules can be pale yellow, light brown, dark brown, or a variegated mix of brown. Lesions are ill-defined, round, and have slightly uneven boundaries. After an acute sunburn, lesions are generally the same size, stellate, strongly defined, and dispersed and discrete.

The differential includes freckles, seborrheic keratosis, spreading pigmented actinic keratosis, and lentigo maligna. The diagnosis is clinical.
​
Treatment for benign solar lentigines is not necessary; however, if removal is desired, cryosurgery or laser surgery are feasible options.
