Introduction
Infancy and early childhood are important periods for the evolution of melanocytic nevi, with the development of new ones and the modification of others.1,2,3 However follow up studies in children of this age are few up to now.4 The aim of the study was to investigate dermoscopic patterns of nevi in children younger than 4 years old and their possible changes on follow-up.
Results
Dermoscopic images of 149 nevi from 129 patients (2-46 months-old, mean age 21 months) were evaluated at the first visit. Patients with positive history for sunburns or phototherapy for neonatal jaundice were not included in the study. Dermoscopic follow-up has been possible for 92 nevi from 77 patients. We considered a pattern as “changed” only if the modification happened within 36 months from the first visit. Patterns were defined according to the 2003 Consensus Conference.
The main changes observed were:
Globular  Globular-reticular (7 nevi, 25,0%)
Globular-reticular  Reticular (5 nevi, 17,9%)
Globular  Reticular (3 nevi, 10,7%)
- No changes were observed for reticular nevi
Pattern abbreviations:
G, globular; R, reticular; G-R, globular-reticular; C, compound; Cb, cobblestone; H, homogeneous; G-Cb, globular-cobblestone; R-Cb, reticular-cobblestone; G-H, globular-homogeneous; R-H, reticular-homogeneous

Conclusions
These data seem to suggest that, at least in childhood, reticular nevi may derive from the PHYSIOLOGICAL MATURATION OF GLOBULAR NEVI.
