Abstract:
We report an extremely rare case of extrarenal testicular Wilms' tumor in a 3-year-old boy with intrabdominal undescended left testis. The patient was admitted because of pain and vomiting, with evidence of a huge abdominal mass. At surgery a large tumor arising from the intrabdominal testis was found. Histology showed the classical triphasic Wilms' tumor elements: epithelial, mesenchymal and blastemal areas. Extrarenal Wilms' tumors account for only 3% of all Wilms' tumors and just -100 cases have been reported in literature. Testicular origin is anecdotic. We present histomorphological, histogenetic, clinical, diagnostic, prognostic and therapeutic features of this rare tumor.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
