Teratomas are neoplasms that arise from pluripotent cells and can differentiate along one or more embryonic germ lines 1. Renal teratoma is an exceedingly rare condition. The primary involvement site is the gonadal tissue; less frequent primary sites of involvement include the anterior mediastinum, retroperitoneum, sacrococcygeal region, brain and the gastrointestinal tract.. The proximity of the genital ridge to the nephrogenic anlage may partly explain how germ cells could be displaced within the kidney.
