McCune-Albright syndrome (MAS) is characterised by the clinical triad
precocious puberty, polyostotic bone dysplasia and cafe-au-lait skin l
esions. Some studies have shown the possibility of multiple endocrinol
ogical disorders in this condition, especially thyroid disorders. We r
eport the case of three girls with MAS and a heteromultinodular thyroi
d at sonography, despite the fact that they were clinically and biolog
ically euthyroid. This raises the question of the follow-up and treatm
ent of these lesions.
