Purpose We explored the diagnostic value of diffusion-weighted MRI (DWI) for tumor characterization, differentiation and therapy monitoring in pediatric patients with extracranial neuroblastic tumors. Materials and Methods All 29 patients (14 girls, median age: 3 years) with neuroblastoma (NB, n = 19), ganglioneuroblastoma (GNB, n = 4) and ganglioneuroma (GN, n = 6) who had had at least one in-house DWI examination since 2005 were identified and retrospectively analyzed. Two independent blinded readers measured ADC values (unit: 10-3 mm(2)/s) and signal intensity ratios (SIRs) of the primary tumor and, if applicable, of the tumor after chemotherapy, metastases and tumor relapse...

Alfred King-Yin Lam
The fourth edition of the World Health Organization (WHO) classification of endocrine tumours contains substantial new findings for the adrenal tumours. The tumours are presented in two chapters labelled as "Tumours of the adrenal cortex" and "Tumours of the adrenal medulla and extra-adrenal paraganglia." Tumours of the adrenal cortex are classified as cortical carcinoma, cortical adenoma, sex cord stromal tumours, adenomatoid tumour, mesenchymal and stromal tumours (myelolipoma and schwannoma), haematological tumours, and secondary tumours...

Neuroblastoma (NB), ganglioneuroblastoma intermixed (GNBi) and ganglioneuroblastoma nodular (GNBn) are neuroblastic tumors that present with a wide range of symptoms and variable prognoses. We retrospectively reviewed the pretreatment clinical (age, sex and tumor stage) and biological (MYCN amplification; and levels of lactate dehydrogenase, ferritin and neuron-specific enolase) characteristics of 279 patients who were diagnosed with pathologically confirmed NB and GNB from January 2005 to December 2015. The median age at diagnosis increased with grade of differentiation (NB: 28...

BACKGROUND: The complete and safe resection of pediatric cervicothoracic tumors, mostly represented by neurogenic tumors, remains a surgical challenge because of the complex anatomy of this region. The transmanubrial osteomuscular-sparing approach (TOSA) is an alternative to isolated or combined cervical and thoracic approaches enabling the control of supra-aortic vessels and nerves through the thoracic inlet. METHODS: We retrospectively reviewed the tumor characteristics, completeness of resection, morbidity, and long-term outcome of patients with cervicothoracic tumors removed by TOSA between 2000 and 2012 in our institution...

PURPOSE: Over recent years, 5-aminoluvolinic acid (5ALA) has been increasingly used for resection guidance in adult high-grade gliomas. However, amongst pediatric patients, publication of intraoperative fluorescence has been limited, with inconsistent outcomes. We describe our experience and intraoperative finding amongst children with various brain tumors that were given 5ALA prior to tumor resection. METHODS: Since October 2014, data regarding intraoperative findings amongst children that received 5ALA prior to tumor resection were prospectively collected...

Neuroblastoma is the most common solid malignant neoplasm in the paediatric age group; accounting for 7% of all childhood malignancies, but neuroblastoma in adult, is a rare occurrence, finding mention in aeons of medical literature with an overall incidence of 1 in 10 million adults/year. We report the case of a 24-year-old male patient presenting with the complaints of progressive abdominal distention of 2 months duration. Multiple Detector Computed Tomography (MD-CT) of abdomen revealed a huge enhancing mass in the retroperitoneum abutting the left kidney, and a subsequent CT-guided biopsy and immunohistochemistry confirmed the diagnosis of ganglioneuroblastoma...

Small round blue cell tumors (SRBCTs) of children and adolescents are often diagnostically challenging lesions. With the increasing diagnostic approach based on small biopsies, there is the need of specific immunomarkers that can help in the differential diagnosis among the different tumor histotypes to assure the patient a correct diagnosis for proper treatment. Based on our recent studies showing cyclin D1 overexpression in both Ewing sarcoma/primitive peripheral neuroectodermal tumor (EWS/pPNET) and peripheral neuroblastic tumors (neuroblastoma and ganglioneuroblastoma), we immunohistochemically assessed cyclin D1 immunoreactivity in 128 cases of SRBCTs in children and adolescents to establish its potential utility in the differential diagnosis...

Ganglioneuroblastoma is a rare tumor with moderate malignancy, which is composed of mature ganglion cells and seen in sympathetic ganglia and adrenal medulla. The diagnosis is possible after cytological and immunohistochemical studies following a needle biopsy or surgical excision. There is no consensus regarding the need for chemo- or radiotherapy after surgery. In this case report, clinical behavior and diagnosis and treatment of the rare tumor cervical ganglioneuroblastoma were discussed.

Kinsbourne syndrome is a rare neurological paraneoplastic syndrome associated with neuroblastic tumors. There are very few literatures on its anesthetic management and interaction with anesthetic agents. The epileptogenic potential of certain anesthetic agents such as ketamine, etomidate, and meperidine might trigger opsoclonus and myoclonus and have an impact on the long-term neurological outcome. The objective of this case report is to discuss the safety of anesthetic agents and their relationship in a patient with Kinsbourne syndrome...

BACKGROUND: Opsoclonus-myoclonus syndrome is a rare clinical condition that has been associated with neuroblastoma. There are few reported examples of ANNA-1/anti-Hu antibodies in children with neuroblastoma and opsoclonus-myoclonus, all in children aged less than three years of age. METHODS: We describe the new onset of focal seizures without alteration of consciousness and opsoclonus-myoclonus in an 11-year-old girl with ANNA-1/anti-Hu positivity and a paraspinal ganglioneuroblastoma...

Pheochromocytoma and Ganglioneuroblastoma are separate diseases and a rare combination in which the diagnosis can only be confirmed by pathological examination after tumor excision. We reported here a case of ganglioneuroblastoma encapsulated in pheochromocytoma. The patient is a woman, 73 years old, hypertensive, with hypothyroidism, associated for 15 years with hypercholesterolemia and hypertriglyceridemia, which had frequent complaints of low back pain. She underwent magnetic resonance and the findings were consistent with the diagnosis of pheochromocytoma...

BACKGROUND: Ewing sarcoma is the second most common bone tumor, occurring mainly in children and young adults. It shows a typical primitive, small round cell morphology and a characteristic fusion oncogene involving EWSR1 and members of the ETS family in most of the cases. Neuronal maturation after chemotherapy is a rare phenomenon and we herein describe such an exceptional case. CASE PRESENTATION: An 8-year old boy was diagnosed with a Ewing sarcoma in the left femur...

BACKGROUND: Ganglioneuroma (GN) and ganglioneuroblastoma intermixed (GNBI) are mature variants of neuroblastic tumors (NT). It is still discussed whether incomplete resection of GN/GNBI impairs the outcome of patients. METHODS: Clinical characteristics and outcome of localized GN/GNBI were retrospectively compared to localized neuroblastoma (NB) and ganglioneuroblastoma-nodular (GNBN) registered in the German neuroblastoma trials between 2000 and 2010. RESULTS: Of 808 consecutive localized NT, 162 (20 %) were classified as GN and 55 (7 %) as GNBI...

BACKGROUND: Although patients with peripheral neuroblastoma (NB; pelvic and thoracic) typically have better outcomes and less aggressive disease compared with patients with abdominal disease, little has been published with regard to the management and outcomes of patients with cervical NB. Herein, we sought to determine the characteristics of cervical neuroblastic tumors and the effect of extent of resection on survival and outcomes. METHODS: We performed a retrospective review of 325 children with neuroblastic tumors at Children's Hospital Los Angeles over a 15-y period (January 1990-February 2015)...
