Abstract
Epidermoid cyst is an unusual and very rarely described lesion in the kidney. We report the case of a 45-year-old woman with no known pathological history who presented with right flank pain accompanied by macroscopic hematuria. The physical examination was unremarkable. The CT scan evoked a malignant tumor in front of a right renal mass with irregular contours. The patient underwent a total right nephrectomy. The nephrectomy specimen received for pathological examination showed macroscopically an encapsulated cystic mass of 4 cm long axis. The cyst lumen was occupied by solid brownish tissue debris. Histologically, the cystic wall was lined by a keratinizing squamous epithelium with accumulation of keratin lamellae in the cystic lumen. Anatomopathological examination concluded to the diagnosis of renal epidermoid cyst.
