Long-term survival after spontaneous rupture of a malignant rhabdoid tumor of the liver.

A 13-month-old girl presented with a large malignant rhabdoid liver tumor that ruptured soon after admission. Six years after an emergency right hepatectomy and subsequent chemotherapy (ifosfamide, vincristine, and actinomycin D), she remains well and disease free. Previously, these rare tumors invariably have been fatal and resistant to multimodal therapy. This is the first report of long-term survival of a patient with a malignant rhabdoid liver tumor.
