Trisomy 18, the second most frequent autosomal trisomy, has an incidence ranging from one per 3,500 to one per 7,000 births.1 Although survival beyond infancy is unusual,1 there are a few reports of relatively long-term survivors.2-4 More than 130 different anomalies have been associated with trisomy 18. Neoplasia, however, is a very rare associated finding. The purpose of this article is to describe a 13-year-old girl with trisomy 18 and Wilms' tumor and to stimulate further interest in the association of aneuploidy and neoplasia.
