[Polyphalangism--a rare anomaly].
Polyphalangism/hyperphalangism is a very rare autosomal dominant anomaly. Polyphalangism is characterized by an extra phalanx between two other phalanges. The abnormality is distinguished from polydactyly in that there are more phalanges in a finger but no more than five fingers to a hand. Polyphalangism can be part of various syndromes, but isolated polyphalangism is very rarely seen. We report the first case of polyphalangism/hyperphalangism in the Danish literature.
