INTRODUCTION: Mesoblastic nephroma first described by Bolande et al.
Solid mixed epithelial and stromal tumors also need to be distinguished from mesoblastic nephroma and metanephric adenofibroma.
The ETV6-NTRK3 gene fusion has previously been detected in pediatric malignant mesenchymal tumors (congenital fibrosarcoma and congenital cellular mesoblastic nephroma).
Congenital fibrosarcoma is another spindle cell sarcoma associated with a characteristic cytogenetic change, the t(12;15)(p13;q26) translocation, not found in adult fibrosarcomas or other sarcomas (123,124) and identical to that described for congenital mesoblastic nephroma.
(3-11) These tumors have been published under the following names in the literature: leiomyomatous renal hamartomas, congenital mesoblastic nephroma in an adult, cystic hamartoma of renal pelvis, solitary multilocular cysts of the kidney, multilocular renal cyst with mullerian-like stroma, and adult metanephric stromal tumor.
(2) Other renal tumors of childhood have been associated with recurring genetic abnormalities: deletion or mutations of WT1 and p53 in some Wilms tumors, t (12;15) creating the ETV6-NTRK3 fusion gene in congenital mesoblastic nephroma, and INI1 deletions or mutations in malignant rhabdoid tumors.
The differential diagnosis for mesoblastic nephroma includes (Figure 1): a.
