Objectives: Wilms' tumor is the most common solid abdominal tumor of childhood. Wilms' tumor is extremely rare in the neonate, with less than 20 well-documented cases. No bilateral lesions in neonates have been described in the literature.
Methods: We report on a neonate who presented with synchronous bilateral Wilms' tumors.
Results: Child underwent bilateral partial nephrectomy, followed by standard chemotherapy, and is now well 2 years after completion of the therapy without any evidence for recurrent disease.
Conclusions: Wilms' tumor should be included in the differential diagnosis of the solid renal mass in the neonate.

Long-term kidney outcomes in survivors of Wilms tumor: a single-center retrospective cohort study.
Pediatr Nephrol
January 2025
Department of Pediatrics, Texas Children's Hospital, Baylor College of Medicine, Houston, TX, USA.
Background: Several studies have investigated long-term kidney outcomes in survivors of Wilms tumor (WT). However, many have small sample sizes, and there is a wide variation in reported outcomes. The aim of this study is to investigate the long-term kidney outcomes in survivors of WT (S-WT), including those patients considered to be at high risk for poor kidney outcomes, and using updated estimated glomerular filtration rate (eGFR) equations.

Establishing genotype-phenotype correlations in disorders of hereditary endocrine neoplasia is important for clinical screening, genetic counseling, prognostication, surveillance, and surgical strategy, and may also provide clues about disease pathogenesis. Important genotype-phenotype correlations are recognized, for example, in pheochromocytoma/paraganglioma and multiple endocrine neoplasia type 2A. The presence of such correlations has been less clear in other familial endocrine disorders associated with primary hyperparathyroidism including multiple endocrine neoplasia type 1 (MEN1), and the hyperparathyroidism-jaw tumor syndrome (HPT-JT).

Background: Circulating tumour cells (CTCs) and tumour-derived extracellular vesicles (tdEVs) have great potential for monitoring therapy response and early detection of tumour relapse, facilitating personalized adjuvant therapeutic strategies. However, their low abundance in peripheral blood limits their informative value. In this study, we explored the presence of CTCs and tdEVs collected intraoperatively from a tumour-draining vein (DV) and via a central venous catheter (CVC) prior to tumour resection.

The Wilms' tumor suppressor WT1 is essential for the development of the heart, among other organs such as the kidneys and gonads. The Wt1 gene encodes a zinc finger transcription factor that regulates proliferation, cellular differentiation processes, and apoptosis. WT1 is also involved in cardiac homeostasis and repair.

Pediatric Surgery Unit, Salesi Children's Hospital, Polytechnic University of Marche, Via Filippo Corridoni, 16, 60123 Ancona, Italy.
Background And Aim: Ex vivo fluorescence confocal microscopy (FCM) systems are innovative optical imaging tools that create virtual high-resolution histological images without any standard tissue processing, either freezing or fixing in formalin and embedding in paraffin. These systems have opened an era that would revolutionize pathological examination by providing rapid, real-time assessments across various pathology subspecialties, potentially replacing conventional methods that are tissue- and time-consuming. This study aimed to present the first utilization of FCM in pediatric surgical oncology, focusing on assessing the benefits, particularly in facilitating rapid and accurate diagnosis.
