Catel-Manzke syndrome: a case report of a female with severely malformed hands and feet. An extension of the phenotype or a new syndrome?

An unusual case of a female infant with Catel-Manzke syndrome is presented. Additional features not previously reported include three accessory ossicles at the bases or associated with the proximal phalanx of the index, middle, ring and little fingers bilaterally. There are also numerous bony abnormalities in both feet. Previous cases have shown no more than 2 accessory ossicles in the hand and these usually involve the index alone. The foot abnormalities are more extensive than any previously seen in this syndrome. This is only the 8th female case out of a total of 27 reported cases.
