Retroperitoneal extragonadal germ cell tumor presenting as a bulky pelvic mass of the obturator fossa.
Extragonadal germ cell tumors (EGGCT) are commonly found in the midline of the body. We report a rare case of a retroperitoneal EGGCT presenting as a bulky pelvic mass located between the left internal and external iliac arteries in a 29-year-old man. His alpha-fetoprotein level was 12946.2 ng/mL and the biopsy of the tumor revealed a nonseminomatous germ cell tumor. After three cycles of chemotherapy (bleomycin/etoposide/cisplatin) followed by resection of all residual tumors, one cycle of salvage chemotherapy (etoposide/ifosphamide/cisplatin) was added. The patient was disease free at 21-month follow up.
