title: Sacrococcygeal teratoma with nephroblastic elements: a case report and review of literature.
abstract: Sacrococcygeal teratoma with nephroblastic elements is very rare. Only 8 cases have been reported up to date. 3 cases were misdiagnosed as extrarenal nephroblastomas and were administered excessive treatments such as chemotherapy and radiation therapy. It has a great significance to distinguish sacrococcygeal teratoma with nephroblastic elements from extrarenal nephroblastoma for their different biological behaviors, therapies and prognoses. Here we report one case of sacrococcygeal teratoma with nephroblastic elements in a newborn with review of the literature. This is the first case of sacrococcygeal teratoma with nephroblastic elements in Chinese to our knowledge.
