AB  - A 29-year-old man presented with a right testicular mass. Serum tumor markers were within normal limits. When compared to a previous computed tomography (CT) scan, a new 4 cm presacral mass was present. He underwent radical right inguinal orchiectomy that demonstrated a mature teratoma and seminomatous components. The patient received four cycles of chemotherapy. Over the courseofchemotherapy,themassgrewinsizeandtherefore he underwent retroperitoneal lymph node dissection. Pathology confrmed it to be a teratoma with negative retroperitoneal lymph nodes. The unusual presentation of an isolated metastasis to the presacral region raises the question of altered lymphatic drainage.
