Solar lentigos or lentigines are very common, especially in people over the age of 40 years. What is lentigo maligna?

Lentigo maligna is also known as Hutchinson melanotic freckle. Lentigo simplex is a common lesion and usually appears in childhood. Key features include mild epidermal acanthosis, increased numbers of uniformly dispersed single melanocytes without atypia in the basal layer and variable basal hyperpigmentation (figures 1, 2). Lentigo simplex is the most common form of lentigo. A single lesion or multiple lesions (lentigines) may be present at birth or more commonly first develop in early childhood. What are brown spots and freckles?
Brown spots and freckles on sun- exposed skin are ephelides (the plural of ephelis) and lentigines (the plural of lentigo). The difference between an ephelis and a lentigo is that an ephelis fades during the winter months while a lentigo persists in the absence of ultraviolet (UV) stimulation.
