This is a report of a trisomy 18 patient who developed Wilms tumor in conjunction with perilobar nephroblastomatosis (NB) at 9 years and 5 months of age. Review of the literature revealed that most patients with trisomy 18 who develop Wilms tumor, do so at a later than expected age for a tumor related to NB, and are females. In this case, no chromosome 11 WT1 mutation was detected by PCR/SSCP analysis, but the tumor had in addition to the trisomy, an isochromosome 7q and loss of heterozygosity at 16q, two mutations that have been linked independently to Wilms tumorigenesis. © 2003 Wiley‐Liss, Inc.
