title: Os penis.
abstract: The presence of os penis in man is very rare. To date only 11 cases have been published. A close study of these cases shows their extreme heterogeneity. We think that the os penis should be considered as a heterotopic bone structure similar to that found in the animal world. To confirm this we present our personal case study.
