Neuroblastoma is a silent tumor with few symptoms. In more than 70% of cases,diagnosis is made after metastasis occurs,with the first signs caused by involvement in the nonprimary site. In only 30% of cases is diagnosis made before metastasis. Neuroblastomas are the most common malignant extracranial solid tumors in children. The majority of tumors develop in the adrenal glands or the retroperitoneal sympathetic chain. They are not benign;they metastasize.
