). Eighty-two patients with high-risk pediatric ACC were evaluated for outcome and prognostic factors: distant metastases and large tumor volume were associated with unfavorable prognosis ( Cecchetto et al . 2017 ). Improved classification and

( Bell et al. 1999 ). Germline mutations in TP53 have been observed in 50–80% of children with apparently sporadic ACC in North America and Europe ( Wagner et al. 1994 , Varley et al. 1999 ). The incidence of pediatric ACC is about 10 times

pediatric ACC is remarkably high (10–15 times the world-wide occurrence) in Southern Brazil because of the segregation of the TP53 hotspot mutation p.R337H. In this region, 90% of pediatric ACC cases harbor this mutation. A free screening of 171
