This report describes a case of large multiple and multilocular epidermoid cysts affecting the left kidney of a 67 old male. The condition was accidentally discovered during the ultrasonography for left loin pain and revealed enlarged left kidney with picture suggestive of hydronephrosis. Grossly, the kidney was distorted cysts that were filled with a cheesy material. The histologic picture of an end stage kidney disease was apparent in the compressed renal parenchyma by these cysts that were identical to an epidermoid cyst elsewhere. In conclusion, although rare, epidermoid cyst of the kidney could cause serious kidney damage leading to an end stage kidney disease. Epidermoid cyst of the kidney could be multiple producing a picture similar to hydronephrosis and broadening the differential diagnosis of multicystic disease of the kidney.
