Abstract

The infiltrating pattern of either nevocellular cells or melanin-laden nevocellular cells and the relationship between this and the size of the nevus were examined. Age-related changes in the infiltrating patterns of these nevocellular cells were also examined. The nevi were classified into 3 types according to the depth of infiltration and into 2 types according to the infiltration pattern of nevocellular cells. Furthermore, each nevus was also classified into 3 types by the location of the melanin-laden nevocellular cells. The relationship between the size of the nevus (small, middle-sized, large) and the infiltrating patterns of nevocellular cells was positive; the larger the nevus becomes, the deeper the infiltration of the nevocellular cells. In the small nevi located only in the head and neck region, the melanin-laden nevocellular cells locate in the papillary dermis in the young and gradually proceed deeper into the dermis with age. This phenomenon was not seen in the nevi on other parts of the body. These obsevations suggest that early dermabrasion of the small nevi located on the head and neck with a laser, may remove the pigmentation caused by the melanin-laden nevocellular cells.
