in a case report by oladipo omoseebi, a female neonate with the stage of 4s neuroblastoma in the right adrenal gland and widespread metastases to the liver at the age of 23 days was presented which had no study prenatal diagnosis. neuroblastoma is the third most commonly occurring malignancy of the pediatric population, although it is extremely rare in the adult population. in adults, neuroblastoma is often metastatic and portends an extremely poor overall survival. our case report documents metastatic neuroblastoma occurring in a healthy 29- year- old woman whose course was complicated by an unusual presentation of. we present the case studies of 2 children ( a male aged 2 and a female aged 4) with stage iv neuroblastoma who received palliative care at the royal children' s hospital, brisbane, in. olfactory neuroblastoma ( on) is a rare type of malignant neoplasm originating from the olfactory neuroepithelial cells of the nasal cavity. on is also known as esthesioneuroblastoma or neuroendocrine carcinoma. neuroblastoma is a cancer that develops from immature nerve cells found in several areas of the body.
neuroblastoma most commonly arises in and around the adrenal glands, which have similar origins to nerve cells and sit atop the kidneys. much of the literature is available mainly on the primary neuroblastoma of abdomen ( retroperitoneum) with its staging system, treatment options, and prognosis. however, literature is sparse when it comes to primary central nervous system ( cns) neuroblastoma. only few case series and isolated case reports are available in the literature. trial evaluating and comparing two intensification treatment strategies for metastatic neuroblastoma patients with a poor response to induction chemotherapy ( veritas) the safety and scientific validity of this study is the responsibility of the study sponsor and investigators. neuroblastoma has been known to occur in the setting of other disorders that are linked to abnormal development of neural crest tissues, such as hirschsprung disease or central congenital hypoventilation syndrome. genome- wide analysis of neuroblastoma from these rare familial cases has identified a genetic defect involved in these cases. neuroblastoma accounts for 50 percent of all cancers in infants, making it the most common tumor in infants younger than 1 year. most children with neuroblastoma are diagnosed before age 5.
the number of cases of neuroblastoma is about the same worldwide, so environmental factors do not seem to play a role.
