Congenital skin tube pedicle associated with the constriction band syndrome.

A very rare case of congenital skin tube pedicle with congenital constriction band syndrome was presented. Only one report concerning this bizarre abnormality could be found in the available literature, and no consideration of its etiology has previously been published. In our case, the skin tube was accompanied by the congenital constriction band syndrome, the cause of which is generally thought to be external factors. Thus the etiology of the congenital skin tube pedicle might be the peeling and rolling of a strip of the fetal skin by external force.
