title: Focal xanthogranulomatous pyelonephritis associated with renal cell carcinoma.
abstract: A case of focal xanthogranulomatous pyelonephritis (XGP) with an associated renal cell carcinoma is presented. The tumor was discovered incidentally during a general surgical procedure. Subsequent evaluation showed a 3 cm mass in the lower pole of an otherwise normal kidney with no evidence of calculus or infection. Radical nephrectomy revealed classic findings of focal XGP with coexistent clear cell carcinoma. The literature describing the rare association between these conditions is reviewed.
