Unusual phenotypes in patients with a pathogenic germline variant in DICER1
AbstractPathogenic germlineDICER1 variants are associated with pleuropulmonary blastoma, multinodular goiter, embryonal rhabdomyosarcoma and other tumour types, while mosaic missenseDICER1 variants in the RNase IIIb domain are linked to cause GLOW (global developmental delay, lung cysts, overgrowth, and Wilms ’ tumor) syndrome. Here, we report four families with germlineDICER1 pathogenic variants in which one member in each family had a more complex phenotype, including skeletal findings, facial dysmorphism and developmental abnormalities. The developmental features occur with a variable expressivity and incomplete penet...

DICER1-Mutated Botryoid Fibroepithelial Polyp of the Parotid Duct: Report of the First Case
AbstractDICER1, a member of the ribonuclease III family, is involved in the biogenesis of microRNAs and, hence, it influences gene expression regulation.DICER1 germline (associated with the inheritedDICER1 syndrome) or somatic mutations have been linked to tumorigenesis in histogenetically diverse benign and malignant neoplasms in different organs including pleuropulmonary blastoma, cystic nephroma, embryonal rhabdomyosarcoma, nasal chondromesenchymal hamartoma, poorly differentiated thyroid carcinoma, thyroblastoma, intracranial sarcoma and gonadal Sertoli-Leydig cell tumors in addition to others. Moreover, rare botryoid ...

Nasal Chondromesenchymal Hamartoma in a Patient With DICER1-Predisposition Syndrome
We present the case of an 8-year-old girl with a history of pleuropulmonary blastoma who presented with worsening nasal obstruction and clinical symptoms of sinusitis secondary to a nasal CMH. The diagnosis of nasal CMH is discussed, as well as DICER1 syndrome. (Source: Pathology Case Reviews)

Whole-Genome Methylation Study of Congenital Lung Malformations in Children
ConclusionsMethylation anomalies already described in lung tumors and also shared by the PPB were found in congenital lung malformations, regardless the histology. The presence of methylation abnormalities is suggestive of a correlation between congenital lung malformations and some step of malignant transformation. (Source: Frontiers in Oncology)

Rare Infant Case of Pulmonary Aspergilloma Highlighting Common Challenges With Voriconazole Dosing
We describe a 6-week-old male-term infant with a pulmonary aspergilloma diagnosed following lobectomy for suspected pleuropulmonary blastoma, with characteristic histopathologic findings and Aspergillus detected by polymerase chain reaction. Intensive testing did not reveal primary or secondary immunodeficiency. During 5 weeks treatment with voriconazole including regular therapeutic drug monitoring and dose adjustment, a level in the target range was never achieved. When the patient developed photosensitivity, treatment was stopped without relapse over 12 months follow-up. Voriconazole dosing is notoriously challenging in...

Pleuropulmonary Blastoma with Hotspot Mutations in RNase IIIb Domain of DICER 1: Clinicopathologic Study of 10 Cases in a Single-Institute Experience
Conclusions: Late detection of solid PPB is associated with poor prognosis. Considering the rarity of PPB disease and the importance ofDICER1 hotspot mutation in pathogenesis,DICER1 hotspot mutation testing and identification in the early cystic stage can improve patient outcomes.Pathobiology (Source: Pathobiology)
