The Pediatric and Developmental Pathology Podcast

In this episode of the Pediatric and Developmental Pathology Podcast, our hosts Dr. Mike Arnold (@MArnold_PedPath) and Dr. Jason Wang speak with Dr. Catherine Gestrich, Pediatric and Molecular Pathologist and Director of Pediatric Molecular Pathology in the Department of Pathology at UPMC Children's Hospital of Pittsburgh and the University of Pittsburgh School of Medicine, and Dr. Qian Wang, Pediatric Pathologist and Cytopathologist, also in the Department of Pathology at UPMC Children's Hospital of Pittsburgh and the University of Pittsburgh School of Medicine. Hear how an incidental pancreatic mass in a young patient led to a diagnostic puzzle, and how chromosomal microarray and next-generation sequencing uncovered a never-before-reported NRAS mutation alongside TP53 alterations and numerous copy number changes in a case of pancreatoblastoma. We also discuss UPMC's approach to molecular testing across adult and pediatric tumors, the Molecular Characterization Initiative for rare pediatric cancers, and their article in Pediatric and Developmental Pathology: Pediatric Pancreatoblastoma with an NRAS Mutation: Expanding the Spectrum of Genetic Alterations in Pancreatoblastoma Featured public domain music: Summer Pride by Loyalty Freak

In this episode of the Pediatric and Developmental Pathology Podcast, our hosts Dr. Mike Arnold (@MArnold_PedPath) and Dr. Jason Wang speak with Dr. Tetyana Nesterenko, Neonatologist in the Division of Neonatal-Perinatal Medicine at UT Southwestern Medical Center, affiliated with Dallas Children's Hospital; Dr. Evelyn Ilori, Hematopathology Fellow at UT Southwestern; Dr. Christine Kahlow, PGY-3 Resident at UT Southwestern; and Dr. Charles Timmons, Pediatric Pathologist and faculty at UT Southwestern, based at Children's Medical Center. Hear how a multidisciplinary team at UT Southwestern approached a full-term neonate's unexplained, rapidly fatal respiratory failure, from the resuscitation and family communication in the NICU to an autopsy that uncovered severe pulmonary hypoplasia and congenital alveolar dysplasia. A standard genetic sequencing panel came back normal, but chromosomal microarray analysis revealed the true cause: a deletion encompassing the TBX4 gene. We discuss the collaboration of their team to identify TBX4 haploinsufficiency at autopsy, and their article in Pediatric and Developmental Pathology: Primary Pulmonary Hypoplasia With Congenital Alveolar Dysplasia Associated With TBX4 Gene Deletion: A Case With Autopsy and Molecular Findings Featured public domain music: Summer Pride by Loyalty Freak
