Pleuropulmonary blastoma is a rare intrathoracic neoplasm almost solely confined to childhood. Survival is poor. The authors report 2 children with extensive intrathoracic disease who are long term survivors after multimodal therapy. Both children received multiagent neoadjuvant chemotherapy, followed by surgical resection to remove all gross tumor. Postoperative chemotherapy was given to both children; radiotherapy was also given in the second case because of a question of positive tumor margins. Experience supports the use of multimodal therapy, including an aggressive surgical approach in the potentially curative treatment of this tumor.

Background And Aims: Primary lung tumors (PLTs) in children are rare, and surgery remains the key to ensure remission. Here we describe the PLTs clinical characteristics, their management, and the pulmonary outcome following surgery.
Methods: We carried out a French national cohort of pediatric PLTs from 2013 to 2023 from the FRACTURE rare pediatric tumors national database.

Localized cystic lung lesions in pediatric patients encompass a spectrum of benign and rare malignant conditions that are quite distinct from cystic lung disease arising in adulthood. The majority have historically fallen under the diagnostic category of "congenital pulmonary airway malformation," a term that has been used to denote a diverse group of diseases ranging in etiology from ectopia to bronchial atresia to mosaic oncogenic mutation or neoplasia. This article reviews the clinical characteristics, gross and histologic features, and pathogenetic underpinnings of congenital pulmonary airway malformation as well as lesions that enter its histologic differential diagnosis.

International Pleuropulmonary Blastoma/DICER1 Registry.
Purpose Of Review: Pleuropulmonary blastoma (PPB) is a rare primary lung neoplasm of infancy and childhood. The purpose of this review is to highlight recent developments in our understanding of PPB and research strategies to facilitate future rare cancer research.
Recent Findings: The International PPB/DICER1 Registry has recently assembled the largest-ever cohorts of type I and Ir PPB and type II and III PPB.
Purpose: Clinical variant analysis pipelines likely have poor sensitivity to the effects on splicing from variants beyond 10 to 20 bases of exon-intron boundaries. Here, we demonstrate the value of SpliceAI to inform curation of rare variants previously classified as benign/likely benign (B/LB) under current guidelines.
Methods: Exome sequencing data from 576 pediatric cancer patients enrolled in the Texas KidsCanSeq study were filtered for intronic or synonymous variants absent from population databases, predicted to alter splicing via SpliceAI (>0.
