[Intramyoma intrauterine device].

This article describes a cases of "missing strings" of a Zipper IUD embeded in an intracavitary myoma. Two attempts with classical procedures failed to remove it and the diagnosis was done after a hysteroscopy complicated with uterine perforation. It is very difficult to assure if the myoma grew around the IUD or it was perforated at the time of its insertion. Histological evidences lead to the first option.
