title: Congenital fibrosarcoma with metastasis in a fetus.
abstract: It is well known that congenital or infantile fibrosarcoma has a much less aggressive behavior than fibrosarcoma in adults, and it rarely metastasizes. We report a case of congenital fibrosarcoma in a 26-wk-old fetus, the diagnosis of which was made by an in utero needle core biopsy. Metastatic tumors were identified at autopsy when the pregnancy was terminated 3 wk later. English literature of metastatic congenital fibrosarcoma was also reviewed.
