황색 육아 종성 신우신염: 증례보고

Abstract

Authors report a case of xanthogranulomatous pylonephritis, characterized by bright yellow bulgiing nodules grossly; a diffuse replacement of the renal parenchyma, already damaged by chronic pyelonephritis by lipid-laden macrophages (foam cells), cholesterol clefts and multimucleated ginat cells within areas of granulomatous reacton 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 kideny, both clinically, bothe and pathologically.
