It is usually dark brown, much darker than ephelids, which are more commonly known as freckles. 1936Arch. Dermatol. & Syphilol. XXXIII. 125 Greater uniformity in the use of the term ‘lentigo’ is needed, and the term should not be used synonymously with ‘ephelis’. Ibid. 109 The subject of lentigo has received scant attention in the American literature, and the term has usually been employed synonymously with ‘ephelis’ or ‘freckle’. 1940Becker & Obermayer Mod. Dermatol. & Syphilol. xviii. 292/1 Lentigo ( in contrast to ephelis, which is the common freckle) is a localized dark brownish macular discoloration, appearing all the way from early adult life to old age, varying in size from a few millimeters in diameter to a centimeter or more. The lesions are distinguished from freckles by the later age of appearance, the darker color, and the tendency to increase in size. 1954Jrnl. Investigative Dermatol. XXII. 219 Lentigo maligna has been classed as melanoma in situ or as a premelanomatous lesion. 1955V.

However, a nodular raised portion indicates the development of more rapidly growing invasive melanoma. |
