Lentigo Pictures - 114 Photos & Images

A lentigo is a small, sharply circumscribed, pigmented macule surrounded by normal-appearing skin. Histologic findings may include hyperplasia of the epidermis and increased pigmentation of the basal layer. A variable number of melanocytes are present; these melanocytes may be increased in number, but they do not form nests. Lentigines 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.

Multiple clinical and etiologic varieties exist. The distinction of a lentigo from other melanocytic lesions (eg, melanocytic nevi, melanoma) and its role as a marker for ultraviolet damage and systemic syndromes is of major significance.
