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.
