A benign solar lentigo, or lentigines (plural), is a small, circumscribed benign pigmented patch surrounded by normal-appearing skin. Lentigines are caused by melanocytic proliferation on the basal layer and may evolve slowly over years, or they may be eruptive and appear rather suddenly. Pigmentation may be homogeneous or variegated, with a color ranging from brown to black. Lentigo is one of the most common form of pigmentation and is caused by sun exposure.
