title: Lentigo.
abstract: A lentigo is a small pigmented macule with a sharply circumscribed border. There are multiple clinical and etiologic forms. Lentigines are often initially identified shortly after birth, although they may appear later in childhood. Certain varieties are associated with systemic abnormalities. Histologic findings include epidermal hyperplasia with increased pigmentation of the basal layer.
