We report a unique case of synchronous functional adrenocortical adenoma and an incidental myelolipoma within ectopic cortical adrenal tissue located in the renal hilum in a child with Beckwith-Wiedemann syndrome and review the association between adrenal gland disorders and myelolipomas. To the best of our knowledge, this is the first documented case of a simultaneous occurrence of these three conditions. A 17-month-old child with Beckwith-Wiedemann syndrome was diagnosed with a left adrenal tumor during complementary radiologic studies. Biochemical investigation before surgery showed elevated blood levels of cortisol and dehydroepiandrosterone hormones. The patient underwent a left adrenalectomy with ipsilateral renal hilar and intercaval-aortic lymph node dissection. Pathology findings revealed a left adrenocortical adenoma and an incidental myelolipoma growing within ectopic cortical adrenal tissue in the renal hilum. The patient is doing well and does not have any current health issues. Patients with adrenal cortex disorders, such as hyperplasias and neoplasms, particularly when associated with hormonal imbalances, may have an increased risk of developing myelolipomas. Whether Beckwith-Wiedemann syndrome may, by itself, contribute to simultaneous occurrence of adrenocortical adenomas and myelolipomas remains to be clarified.

Congenital hyperinsulinism in the Ukraine: a 10-year national study.
Front Endocrinol (Lausanne)
January 2025
Department of Clinical and Biomedical Science, University of Exeter Medical School, Exeter, United Kingdom.
Introduction: Congenital Hyperinsulinism (CHI) has not been previously studied in Ukraine. We therefore aimed to elucidate the genetics, clinical phenotype, histological subtype, treatment and long-term outcomes of Ukrainian patients with CHI.
Methods: Forty-one patients with CHI were recruited to the Ukrainian national registry between the years 2014-2023.
Infant With Beckwith-Wiedemann Requiring Transplant for Hepatic Mesenchymal Hamartoma.

Thomas Jefferson University Hospital, Philadelphia, Pennsylvania, USA.
Background: Liver transplantation for unresectable, benign hepatic lesions is rare. Hepatic mesenchymal hamartomas (HMH) are benign, cystic tumors that arise mostly in pediatric populations and can cause compressive symptoms. HMH is rarely associated with placental mesenchymal dysplasia (PMD) and Beckwith-Wiedemann syndrome (BWS).

Liver masses in children with underlying systemic disease or a predisposing syndrome can be benign or malignant, ranging from focal fat to hepatocellular carcinoma (HCC). Knowledge of the underlying condition, the pathophysiologic effect on the liver, and the development of liver disease and specific liver lesions allows radiologists to guide imaging with regard to modality and frequency and give recommendations for biopsy when appropriate. In some predisposition disorders, such as Beckwith Wiedemann spectrum, familial adenomatous polyposis syndrome, and tuberous sclerosis complex, established guidelines for imaging screening exist.

To assess the suitability of genome sequencing (GS) as the second step in the diagnostics of patients with the features of 11p15.5-associated imprinting disorders (ImpDis: Silver-Russell syndrome [SRS], Beckwith-Wiedemann syndrome [BWS]), we performed short-read GS in patients negatively tested for imprinting disturbances. Obtaining a genetic diagnosis for patients with the features of these syndromes is challenging due to the clinical and molecular heterogeneity and overlap, and many patients remain undiagnosed after the currently suggested stepwise diagnostic workup.

Pediatrics and Adolescent Medicine, Faculty of Medicine, University of Augsburg, 86156, Augsburg, Germany.
Purpose: Cancer predisposition syndromes are genetic disorders that significantly raise the risk of developing malignancies. Although the malignant manifestations of cancer predisposition syndromes are well-studied, recognizing their non-malignant features is crucial for early diagnosis, especially in children and adolescents.
Methods: A comprehensive literature search was conducted using the PubMed database, focusing on non-malignant manifestations of cancer predisposition syndromes in children and adolescents.
