<jats:title>Abstract</jats:title><jats:sec><jats:title>Background and aims</jats:title><jats:p>Core needle biopsies (CNB) are less invasive, cause less morbidity, and have lower costs than open biopsies (OB). However, the number of studies reporting CNB accuracy in pediatric tumors is limited and series are small. The aim of this study is to investigate if CNB diagnosis is concordant with the final diagnosis in pediatric solid non‐central nervous system (CNS) tumors.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>Data from all patients treated in a single center between November 2014 and December 2019 were collected from the national pathology database and from local medical records. Data collection included age, sex, CNB diagnosis, final diagnosis, number of cores obtained, number of cores used for histology, cumulative core length, greatest dimension of the lesion, lesion volume, and complications.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Out of 361 CNB, 95.6% (345/361) provided a diagnosis. A resection or follow‐up biopsy was performed in 201 cases. The final diagnosis was concordant with the CNB in 100% (201/201) of cases. The age, number of cores used for histology, and the greatest dimension of the lesion did not significantly differ between diagnostic and nondiagnostic CNB. The cumulative core length of diagnostic CNB was significantly higher than in the nondiagnostic group (24.72 mm vs. 13.37 mm, <jats:italic>p</jats:italic>‐value .022). Complications occurred in 2.1% (7/337) of CNB procedures. Molecular analysis was successful in 228/233 (98%) of cases in which it was performed.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>CNB diagnosis is highly concordant with the final diagnosis and the diagnostic rate is high. The complication rate in CNB is low.</jats:p></jats:sec>
