Eruptive Nevi

Abstract

To the Editor.— Nevus cell nevi, or pigmented nevi, are benign tumors of the skin that contain nevus cells. Only 3% of infants are born with nevi. However, the incidence increases in infancy and childhood, with a peak during puberty and adolescence. During adolescence and young adulthood, the average number of nevi found is 20 to 40 per person.¹ The life cycle of the nevus is to evolve from a junction nevus into a compound nevus and then into an intradermal nevus. By adulthood, the predominant nevus is often destroyed by being replaced by fibrous or fatty tissue. Crops of pigmented nevi may develop in patients over a period of a few weeks. This is probably due to stimulation of multiple fociat the same time. It occurs most commonly during pregnancy and puberty. The nevus cells may have been present, but unrecognized, until stimulated by hormonal influences
