Early detection of adrenocortical carcinoma in a child with Li-Fraumeni syndrome
We report an early detection of cancer in a child with Li-Fraumeni syndrome. The proband was a 3-year-old male with a primitive mesenchymal tumor. Genetic analysis showed a germline TP53 mutation in codon 220 exon 6, which changed TAT --> TGT and resulted in a tyrosine-to-cysteine amino acid substitution (Tyr220Cys). The younger sister at risk was followed, and an asymptomatic adrenal cortical carcinoma was detected 3 years later. The report highlights the importance of genetic counseling and provides an example of early detection of cancers in childhood LFS carriers.
