Abstract
Background
Neurofibromatosis type 1 (NF1) is one of the most common genodermatoses. It can affect every organ and is associated with an increased risk of benign and malignant tumors. Most common tumoral locations involve nervous system and soft tissues but a large variety of tumors have been described. So far, hepatoblastoma in a patient with NF1 has been reported twice in the literature.
Case presentation
A liver mass was discovered in a 11 year-old girl with NF1 leading to a diagnosis of epithelial hepatoblastoma with pulmonary metastasis. Targeted analysis on blood revealed a germline NF1 missense variant. Exome sequencing, RNA-seq and methylation analyses performed on tumoral and metastatic samples confirmed the germline NF1 variant and showed classical driver variants for hepatoblastoma.
Conclusions
We present here the third case of hepatoblastoma in a patient with NF1 and discuss the possible link between this rare tumor and this neurocutaneous genetic condition.
期刊介绍：
The aim of Cancer Genetics is to publish high quality scientific papers on the cellular, genetic and molecular aspects of cancer, including cancer predisposition and clinical diagnostic applications. Specific areas of interest include descriptions of new chromosomal, molecular or epigenetic alterations in benign and malignant diseases; novel laboratory approaches for identification and characterization of chromosomal rearrangements or genomic alterations in cancer cells; correlation of genetic changes with pathology and clinical presentation; and the molecular genetics of cancer predisposition. To reach a basic science and clinical multidisciplinary audience, we welcome original full-length articles, reviews, meeting summaries, brief reports, and letters to the editor.
