title: Intrarenal epidermoid cyst.
abstract: Epidermoid cyst is a very unusual cause of renal mass. Only two cases have been reported in the English or French literature. We have encountered this entity in a 4-year-old Haitian boy investigated for urinary frequency. This diagnosis must be included in the differential of coarse calcified intrarenal masses.
