Wilms’ tumor (WT)/ Nephroblastoma is the second common abdominal malignancy and most common malignant renal tumor in children . Twelve % of WT patients have metastases at initial presentation . Common hematogenous metastatic site of WT include the lung, liver, and contralateral kidney. Less common sites include the bone, skin, brain, and orbit . The lung is most common hematogenous metastatic site. The lymphatic spreads to lymph nodes are the most common. The rare site of metastasis are mediastinum and testis [1-12].
In adults most frequent primary tumors metastatic to spermatic cord and epididymis are carcinomas from the stomach, prostate, colon, pancreas, appendix, and renal (renal cell carcinoma) [13,14].
It is utmost important to evaluate the genitalia in pediatric patients presenting with renal lump, as there may be syndromic association, (cryptorchidism, pseudohermaphroditism), vericocele (tumor compressing testicular veins) hydrocele (subclinical metastasis having reactive hydrocele ), patent processes vaginalis etc [15-16]. To the best of our search (all languages, both indexed non indexed journal) with the key words testicular metastasis, paratesticular metastasis, metastatic Wilms’ tumor in the literature from 1928 to 2016, we found 12 cases of testicular/ paratesticular metastasis of WT [1-12]. We excluded the cases of extrarenal scrotal WT (scrotal WT without primary renal involvement) arising from heterotropc anlage . Author here reported a rare case of WT with synchronous epsilateral testicular metastasis, with discussion of diagnostic and therapeutic approach for children presenting with renal lump and testicular mass.
