In adult Wilms tumor

The characteristic findings of isochromosome 7q, lack of trisomy or tetrasomy for chromosome 12, and absence of persistent renal blastema suggest that the pathogenesis of Wilms’ tumors in adults may be different than in the pediatric population. These genetic features may be helpful in distinguishing adult Wilms’ tumors from other primary renal tumors. (11117788)
