Congenital neuroblastoma is the most frequent malignant solid tumor in the neonatal period. The clinical presentation is usually either by prenatal diagnosis or by palpation of an abdominal mass. Staging allows classifying it according to risk groups with a different prognosis and treatment. In the neonatal period, it is characterized by a high rate of spontaneous regression and good prognosis (disease-free survival at 5 years greater than 90 %). We present a clinical case of congenital neuroblastoma whose presentation, shock and hypertension, was only described on a previous occasion. Antihypertensive treatment along with systemic chemotherapy produced clinical control and patient improvement.

Risk of developing neuroblastoma influenced by maternal stressful life events during pregnancy and congenital pathologies.
Pediatr Blood Cancer
February 2025
Pathology Department, Medical School, University of Valencia, Valencia, Spain.
Objective: A retrospective multicenter study to investigate the potential association between descriptive information related to pregnancy history and perinatal features and the risk of neuroblastoma (NB) in children.
Study Design: Data from 56 mothers during 105 pregnancies (56 cases of NB, 49 control siblings) were collected through face-to-face or telephone interviews with mothers of children diagnosed with NB, along with information extracted from Health System databases. Descriptive information related to (a) pregnancy history as maternal stressful life events with perceived distress during pregnancy, weight gain, alcohol and tobacco consumption, mode of delivery and gestational age; and (b) perinatal features as congenital pathologies, weight at birth and type of feeding were examined to identify potential risk factors for NB.
Congenital melanocytic nevus syndrome: An association between congenital melanocytic nevi and neurological abnormalities.

Article Synopsis
- Congenital melanocytic nevus syndrome is characterized by the presence of congenital melanocytic nevi (CMN) along with various neurosystem abnormalities, primarily due to mutations in the NRAS gene.
- CMN appears as collections of melanocytes on the skin and can be classified by size and various clinical features like location and color, while neurological issues might include seizures and developmental delays.
- Early MRI screening of the central nervous system in infants is essential for assessing potential neurological risks, and while some outcomes are favorable with normal MRI results, severe complications can arise if melanoma develops.
Prenatal Exposure to Herbicide 2,4-Dichlorophenoxyacetic Acid (2,4D) Exacerbates Zika Virus Neurotoxicity In Vitro and In Vivo.
Environ Toxicol
September 2024
Laboratorio de Microbiologia Celular, Instituto Oswaldo Cruz, FIOCRUZ, Rio de Janeiro, Brazil.
Article Synopsis
- - The Zika virus can cause Congenital ZIKV syndrome (CZS) during pregnancy, leading to malformations like microcephaly, with varying prevalence across Brazil, particularly in the Northeast and Central-West regions.
- - A study found that exposure to the agrochemical 2,4-dichlorophenoxyacetic acid (2,4D), commonly used in Brazil, worsens the neurotoxic effects of ZIKV in human cells and mice models, resulting in smaller brain size and increased cell death.
- - There is a notable correlation between the prevalence of CZS and the use of 2,4D in certain Brazilian regions, suggesting that this agrochemical may enhance the transmission of Z
A disease-associated PPP2R3C-MAP3K1 phospho-regulatory module controls centrosome function.

Centrosomes have critical roles in microtubule organization, ciliogenesis, and cell signaling. Centrosomal alterations also contribute to diseases, including microcephaly, cancer, and ciliopathies. To date, over 150 centrosomal proteins have been identified, including several kinases and phosphatases that control centrosome biogenesis, function, and maintenance.
