| Abstract |
|
Authors report a case of xanthogranulomatous pyelonephritis, characterized by bright yellow bulging nodules grossly; a diffuse replacement of the renal parenchyma, already damaged by chronic pyelonephritis by lipid-laden macrophages (foam cells), cholesterol clefts and multinucleated giant cells within areas of granulomatous reaction microscopically. Features of fibrosis, extending to the perinephric fat, hydronephrosis, and chronic suppurative nephropathy due to staghorn calculi were also present.
This lesion is important to recognize because it may be confused with clear cell carcinoma of the kidney, both clinically, both and pathologically.
