Abstract
- A three year old girl with a left renal teratoid Wilms tumor is reported. The tumor was located both inside and outside the kidney parenchyme, to form a well encapsulated mass containing two lobulated solid and cystic masses. The tumor consists predominantly of otherwise typical Wilms tumor irregularly mixed with teratoid tissue elements such as intestinal tract, mucous glands with argentaffin cells, goblet cells and transitional epithelium. These heterologous elements were regarded as diverse epithelial differentiation of totipotent cells in certain nephrogenetic period, and this tumor was considered to be hest called "teratoid Wilms tumor".
