Childhood Kidney Tumors

NewYork-Presbyterian treats all types of kidney tumors in children, including:

• Wilms tumor. Wilms tumor is the most common type of kidney cancer found in children, involving one or both kidneys. Ninety percent of Wilms tumor cases can be cured.
• Renal cell cancer. Renal cancer typically affects adolescents between 15 and 19 years old. Also called renal cell carcinoma, the disease usually starts in the lining of the small tubes of the kidney.
• Rhabdoid tumor of the kidney. This type of kidney cancer most frequently affects infants and young children. Because it grows and spreads quickly, it is often at an advanced stage when diagnosed.
• Clear cell sarcoma. This is a rare form of kidney cancer more common in children under 3 years of age.
• Congenital mesoblastic nephroma. This kind of tumor is typically found before birth or within the first year of being born. It is the most common kidney tumor diagnosed in infants under 6 months (in males more than females) and has a high curability rate.
• Ewing sarcoma. This type of kidney cancer is more common in young adults and can spread quickly throughout the body.
• Primary renal myoepithelial carcinoma. This rare, quick-spreading form of cancer can affect the soft tissues and internal organs such as the kidney.
• Cystic partially differentiated nephroblastoma. This rare form of kidney tumor is comprised of cysts.
• Multilocular cystic nephroma. These are benign (noncancerous) tumors made of cysts, most commonly found in biologically female people, infants, and young children.
• Primary renal synovial sarcoma is a rare form of soft tissue sarcoma comprised of cyst-like tumors of the kidney. It is usually diagnosed in young adults and can spread quickly.
• Anaplastic sarcoma of the kidney. This is an extremely rare and newly recognized type of kidney cancer, most common in children under the age of 15.
