[Wilms tumor and Bloom syndrome].

Unlabelled: Bloom syndrome is characterized by growth failure, skin anomalies with sun sensitivity, minor anatomic defects, excessive chromosomic fragility and usually severe immune deficiency. The chromosome fragility predisposes these children to the development of hematologic malignancies and solid tumors.

Case Report: Morgan, a 4-year-old boy with Bloom syndrome, developed a Wilms tumor.
