Xanthogranulomatous Pyelonephritis and Amyloidosis - Abstract
The association of systemic amyloidosis and xanthogranulomatous pyelonephritis is extremely uncommon with fourteen cases described in the literature. We present the case of a 68-year-old woman who underwent nephrectomy for an inflammatory mass in her non-functioning left kidney. Histopathological examination of the specimen revealed, in addition to a xanthogranulomatous pyelonephritis, deposits of amyloid in the interstitial blood vessels and in the perirenal adipose tissue. Our purpose is to describe this case, given the unusual association of these entities.
