Abstract
A 30-year-old white man presented with gyneco mastia over 1 month. The right testicle showed a benign cyst on ultrasound, and a biopsy of the left testicle was normal. The beta-subunit of human chorionic gonadotrophin (β-HCG) was elevated at 5000 IU/ml; therefore, a computed tomography (CT) scan was ordered and showed a 3–4 cm mass at the bifurcation of the aorta. This mass proved to be hemorrhagic choriocarcinoma, and it was successfully removed, with all other retroperitoneal nodes being negative for cancer. No normal lymph node tissue could be discerned accompanying the choriocarcinoma, suggesting that this might be an extra-gonadal primary rather than a metastasis from a subclinical testicular lesion. Postoperatively, the β-HCG dropped to nondetectable levels.
