Abstract
We report on a 12-year-old boy with Costello syndrome born to consanguineous (first cousins once removed) parents, supporting the hypothesis of recessive transmission of this syndrome. At age 11 years, the patient developed a bladder carcinoma, a rare pediatric tumor not previously described in Costello syndrome. This suggests that an increased risk of malignancy may be part of this condition.
