Sotos syndrome is a rare disorder of statural overgrowth in children. Peculiar facies, pre- and post-natal overgrowth and advanced bone age are the main clinical findings; developmental delay may be present. The Authors report a case of Sotos syndrome followed until adult height and describe the pattern of growth. The girl showed the typical findings of the syndrome together with premature pubarche and premature pubertal development. Since precocious puberty determines an increase of growth during childhood, the Authors suggest that Sotos syndrome should be considered and excluded in girls with premature pubertal development.
