pyelonephritis: Clinical experience with 41 cases.
Both lesions had xanthogranulomatous
inflammation with numerous foamy histiocytes and extensive fibrosis extending into the muscularis propria.
pyelonephritis (XGPN) is a rare clinicopathological syndrome that is unique among the various inflammatory conditions of the kidney, and it closely mimics renal cell carcinoma, both clinically and radiologically.
lesions can infiltrate the soft tissues, central nervous system, retroperitoneum, and viscera.
A rare case of xanthogranulomatous
pyelonephritis (XGPN) in a horseshoe kidney is presented with emphasis on the computed tomography (CT) findings.
Pseudoaneurysm of the Cystic Artery Associated with Xanthogranulomatous
The differential diagnosis of a renal mass includes hydronephrosis, polycystic kidney disease and infrequently xanthogranulomatous
This review will specifically address acquired immunodeficiency syndrome (AIDS) nephropathy, acute and chronic pyelonephritis, renal and perirenal abscess, emphysematous pyelonephritis, emphysematous pyelitis, malacoplakia, diffuse and focal xanthogranulomatous
pyelonephritis, fungal infections, tuberculosis (TB), and replacement lipomatosis.
26,27) One view is that, excluding spontaneous xanthomas that develop in hyperlipidemic states and immunologic or storage disorders resulting in defective phagocytosis, all other instances of xanthogranulomatous
reactions are the consequence of lipid phagocytosis by macrophages secondary to hemorrhage, suppuration, or necrosis.
Histologic examination of the resected specimen identified a xanthogranulomatous
tissue reaction adjacent to a Warthin's tumor.
52) In rare situations, nonneoplastic processes, such as xanthogranulomatous
pyelonephritis or malakoplakia, may present as a tumoral mass clinically, grossly, or microscopically.
Also described as retractile mesenteritis, liposclerotic mesenteritis, xanthogranulomatous
mesenteritis, systemic nodule panniculitis, and mesenteric Weber-Christian disease, sclerosing mesenteritis appears to have an increased incidence in men with a mean age of 60 years.
