Short‐term cultures of three hepatoblastomas were analyzed cytogenetically. Trisomy 2, trisomy 20, and a deletion of 17p were found as the sole abnormalities, yielding the karyotypes 47,XY, + 2; 47,XX, + 20; and 46,XX,del(17)(p12)/46,XX. This is the first reported case of deletion of 17p as the sole chromosomal abnormality in a hepatoblastoma and the first reported case of trisomy 20 without double minute chromosomes as a sole chromosomal abnormality in hepatoblastoma.
