[G. F. d'Acquapendente and Don Carlo Medici's gibbosity].

Don Carlo dei Medici (1595-1666) is the son of Ferdinando I (1549-1609), Granduca of Tuscany, and becomes Cardinal of Catholic Roman Church in 1615. In 1604 Fabrizio d'Acquapendente is called in Florence to treat him, because of an aggravation of his health, and of his congenital neck's gibbosity. The recent paleopathological researches have diagnosed his congenital cervical gibbosity as effect of the Klippel-Feil's syndrome, and characteristic lesions of tubercolosis.
