Renal squamous cell carcinoma mimicking xanthogranulomatous pyelonephritis: Case report and review of literature

Primary renal squamous cell carcinoma (SCC) is a rare primary malignancy of the kidney. Diagnosis is usually delayed because of its lack of characteristic clinical and imaging features and inherent aggressive nature. We present a case of primary renal SCC in a 66-year-old woman with bilateral renal calculi and a complex right lower pole renal mass. The diagnosis of primary renal SCC was established based on the histopathology after right nephrectomy.
