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.
性腺外生殖细胞肿瘤（EGGCT）常见于身体中线部位。我们报告了一例罕见的腹膜后EGGCT病例，该病例表现为一名29岁男性患者盆腔内巨大肿块，位于左髂内动脉和髂外动脉之间。他的甲胎蛋白水平为12946.2 ng/mL，肿瘤活检显示为非精原细胞瘤性生殖细胞肿瘤。在进行三个周期的化疗（博来霉素/依托泊苷/顺铂）后切除所有残留肿瘤，随后增加了一个周期的挽救性化疗（依托泊苷/异环磷酰胺/顺铂）。患者在21个月的随访中无疾病复发。
