[len-ti´go] (L.) a flat, brownish pigmented spot on the skin due to increased deposition of melanin and an increased number of melanocytes; a freckle. (See Atlas 2, Part O.)lentigo malig´na (malignant lentigo) see melanoma" >lentigo maligna melanoma.senile lentigo (lentigo seni´lis,) (solar lentigo) a small smooth round brownish patch appearing on the face, neck, or back of the hands of many older people, caused by an increase in pigment; these are entirely harmless. Although these spots are associated with aging, it is not age that is the principal cause but many years of exposure to sun and wind. Called also liver spot.

len·ti·go ma·lig·na

a brown or black mottled, irregularly outlined, slowly enlarging lesion resembling a lentigo in which there are increased numbers of scattered atypical melanocytes in the epidermis, usually occurring on the face of older persons; after many years the dermis may be invaded and the lesion is then termed lentigo maligna melanoma.
