Conclusion
Renal SCC with coexisting XGPN is an extremely rare presentation and only four cases have been previously reported in the English medical literature. A positive diagnosis for this rare combination of diseases was established, based on pathological and immunohistochemical examinations after radical nephrectomy. Poor prognosis has been reported in such cases. Malignancies should be considered in patients with a long-standing history of urolithiasis.
