Stroma-predominant Wilms tumor with teratoid features: report of a rare case and review of the literature.

We describe the case of a 4-year-old boy with a unilateral right-sided Wilms tumor with stromal predominance and teratoid features, which was localized to the kidney and hence, was completely resected. The pediatric surgeon and pathologist, both should be aware of this rare appearance of nephroblastoma so as to avoid the highly toxic chemotherapy and radiotherapy in such patients.
