Ovarian dysgerminoma is a rare type of germ cell tumor. The majority of patient relapses occur within 2 years of diagnosis. Here, we report the case of a 74-year-old woman with a history of ovarian dysgerminoma 39 years earlier. The patient visited the hospital presenting with heartburn. An abdominal computed tomography (CT) revealed a right retroperitoneal mass, and a primary retroperitoneal tumor was suspected. She underwent surgical resection of the retroperitoneal tumor. Histological examination confirmed a metastatic dysgerminoma to the retroperitoneum. Postoperative CT showed paraaortic and cervical lymph node metastases. The patient was treated with bleomycin, etoposide, and cisplatin chemotherapy. This case demonstrates the difficulties that may be encountered in the differential diagnosis of a retroperitoneal mass and underlines the necessity for understanding a patient's clinical history.
卵巢无性细胞瘤是一种罕见的生殖细胞肿瘤。大多数患者在诊断后2年内复发。在此，我们报告一例74岁女性患者，39年前有卵巢无性细胞瘤病史。该患者因烧心症状前来就诊。腹部计算机断层扫描（CT）显示右侧腹膜后肿块，怀疑为原发性腹膜后肿瘤。她接受了腹膜后肿瘤的手术切除。组织学检查证实为腹膜后转移性无性细胞瘤。术后CT显示主动脉旁和颈部淋巴结转移。该患者接受了博来霉素、依托泊苷和顺铂化疗。本病例展示了腹膜后肿块鉴别诊断中可能遇到的困难，并强调了了解患者临床病史的必要性。
