[Diffuse xanthogranulomatous pyelonephritis in childhood]

Xanthogranulomatous pyelonephritis is a rare disease and rare cause of suppurative proliferative pseudotumor in children. An accurate diagnosis is difficult because of its clinical, radiological, sonographical and pathologic-anatomical similarities to renal tuberculosis. After removing the diseased kidney the prognosis is excellent. A 6-year old boy with xanthogranulomatous pyelonephritis is reported.
