Speckled lentiginous nevus.

Speckled lentiginous nevus is, we feel, a distinctive nevocytic disorder and a clinical variety of nevus-cell nevus. The speckled areas show varying histological patterns that range from nevus incipiens to junctional and compound nevi. The background shows histological features of lentigo simplex. It is our contention that speckled lentiginous nevus should be separated from nevus spilus and nevus spilus tardus (Becker's), which we consider to be variants of epidermal nevus.
