Neuroblastoma

<p>The term neuroblastoma is commonly used to refer to a spectrum of neuroblastic tumors (including neuroblastomas, ganglioneuroblastomas, and ganglioneuromas) that arise from primitive sympathetic ganglion cells. Neuroblastomas, which account for 97 percent of all neuroblastic tumors, are heterogeneous, varying in terms of location, histopathologic appearance, and biologic characteristics. They are most remarkable for their broad spectrum of clinical behavior, which can range from spontaneous regression, to maturation to a benign ganglioneuroma, or aggressive disease with metastatic dissemination leading to death.</p>
