[Stage II focal xanthogranulomatous pyelonephritis].

Abstract

OBJECTIVE:

To report a case of focalized stage II xanthogranulomatous pyelonephritis and the diagnostic difficulties encountered.

METHODS:

A 63-year-old female consulted at the emergency services for fever during the last two months and right lumbar pain. Urinary cultures were negative. A CT scan showed a poorly-defined heterogeneous mass in the lower pole of the right kidney. Fine needle punction-aspiration biopsy was compatible with renal cell carcinoma. The patient underwent radical nephrectomy.

RESULTS:

The histopathological study showed focalized stage II xanthogranulomatous pyelonephritis but no evidence of neoplasia.

CONCLUSIONS:

Xanthogranulomatous pyelonephritis can mimic the clinical, cytological and imaging features of renal neoplasia.
