An unusual cystic lesion histologically similar to autosomal dominant polycystic kidney disease in a child with aniridia and del 11p13.

Abstract

The association of Wilms tumor with an interstitial deletion on the short arm of chromosome 11 is well established. Specifically, the 11p13 band has been implicated in the syndrome of Wilms tumor, aniridia, genitourinary abnormalities and mental retardation. Only rarely have other renal lesions been associated with the chromosomal abnormality del 11p13. We report a case of a segmental cystic lesion, histologically akin to autosomal dominant polycystic kidney disease, in a child with aniridia and the del (11)(p12p14) karyotype.
