Maffucci syndrome is a very rare disorder in which multiple benign tumors of cartilage develop within the bones (such tumors are known as enchondromas). The tumors most commonly appear in the bones of the hands, feet, and limbs, causing bone deformities and short limbs.
It is named for the Italian pathologist Angelo Maffucci who described it in 1881. Fewer than 200 cases of this syndrome have been reported.
