ABSTRACT
Cholesteatoma of the upper urinary tract is a rare nonmalignant condition histologically characterized by keratinizing desquamative squamous metaplasia (KDSM). Until now about 80 cases including one case from Korea have been reported. Cholesteatoma shows microscopic features of squamous metaplasia of the transitional epithelium and keratinization. These changes with subsequent desquamation of the superficial epithelial layers explain clinical manifestations of the disease. Flank pain, passage of cornified material in the urine and a filling defect on the IVP constitute the characteristic triad. Most cases were managed by extensive ablative surgery for fear of malignant potential. We report a case of renal cholesteatoma which was misdiagnosed as renal stone in 58 year-old female patient who had been suffered from intermittent left flank pain.
