Abstract
- Most patients with Wilms tumor do not have associated congenital anomalies. However, significant associations with congenital urinary tract defects, hemihypertrophy, and sporadic aniridia have been reported. Horseshoe kidney is a congenital anomaly in which both kidneys are fused at the lower poles with renal parenchymal or fibrous isthmus. The risk of malignancy in a horseshoe kidney is probably not different from that in a normal kidney. But Wilms tumor are more common in patients with horseshoe kidney than in the general population. We report a case of Wilms tumor arising in a horseshoe kidney with brief review of related literatures.
