Two cases of<unk>  in which their tumor cells expressed a USP6-PPP6R3 fusion gene had highly aggressive, locally invasive, repeatedly recurrent (after surgical removal), and progressively enlarging tumors over 2 and ten years. One case developed multiple metastases (i.e. spread of tumor to different parts of the body) that along with the primary tumor site were partially controlled with radiation therapy. The other case was treated by wide surgical resection of the tumor; this case did not have metastatic disease and one year after the wide resection had no recurrences.
