  • Title: Large teratoma at aortic bifurcation: an unusual metastasis of testicular cancer.
    Author: Zhang Y, Byler T, Landas S, Ekroth M, Shapiro O.
    Journal: Can J Urol; 2012 Apr; 19(2):6201-3. PubMed ID: 22512966.
    Abstract:
    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 course of chemotherapy, the mass grew in size and therefore he underwent retroperitoneal lymph node dissection. Pathology confirmed 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.
