Although Wilms Tumor is by far the most common solid tumor that develops in the kidney in pediatric patients, other tumors that might be present include mesoblastic nephroma (typically in infants), clear cell sarcoma, rhabdoid tumor, and renal cell carcinoma (in adolescents, though more common in adults). (hopkinsmedicine.org)
Other tumors such as rhabdoid tumors of the kidney, clear cell sarcoma of the kidney and mesoblastic nephroma occur in the kidney but are not Wilms tumors and have different prognoses and treatment. (luriechildrens.org)

Infantile fibrosarcoma2
Oncogenic fusions involving neurotrophic receptor tyrosine kinase (NTRK) genes are being increasingly identified in a range of mesenchymal tumours unrelated to infantile fibrosarcoma or cellular congenital mesoblastic nephroma, where the canonical ETV6-NTRK3 fusion was first described more than two decades ago.
