Abstract
|
|
|
Cholesteatoma in the kidney and ureter is accumulations of waxy, gray flakes of keratin materials, secondary to squamous metaplasia of the transitional epithelium. Herein, we describe a case of cholesteatoma in the renal pelvis of a 64-years-old
woman,
and give a brief review of the literature. In the renal pelvis of the left kidney was a 6cm-sized cystic lesion filled with a thick, flaky, grayish, cornified material. Microscopically, the cystic area showed calyceal and pelvic structures being
replaced by keratinizing stratified squamous epithelium.
