A 72-year-old woman was transferred to our hospital after being diagnosed with retroperitoneal and ovarian tumors. Abdominal computed tomography revealed a well-defined mass lesion measuring 35 mm on the dorsal side of the descending part of the duodenum that was surrounded by the head of the pancreas and inferior vena cava. In addition, a cystic mass measuring 90 mm was found in the pelvis. Hence, the patient was diagnosed synchronous retroperitoneal tumor and teratoma. Laparoscopic retroperitoneal tumor resection and right adnexectomy were performed. The pathological findings indicated that the retroperitoneal tumor was a diffuse large B-cell lymphoma and the pelvic tumor was a mature cystic teratoma of the ovary. On the basis of the computed tomography findings, we judged that the tumor had a poor tendency to infiltrate and could be peeled off and resected using laparoscopic surgery. In this rare case, the retroperitoneal tumor and mature teratocarcinoma were simultaneously resected laparoscopically.
一名72岁女性在被诊断出患有腹膜后和卵巢肿瘤后被转至我院。腹部计算机断层扫描显示，在十二指肠降部背侧有一个边界清晰的肿块，大小为35毫米，被胰头和下腔静脉包围。此外，在盆腔发现一个90毫米的囊性肿块。因此，该患者被诊断为同步性腹膜后肿瘤和畸胎瘤。实施了腹腔镜腹膜后肿瘤切除术和右侧附件切除术。病理结果表明，腹膜后肿瘤为弥漫性大B细胞淋巴瘤，盆腔肿瘤为卵巢成熟囊性畸胎瘤。根据计算机断层扫描结果，我们判断该肿瘤浸润倾向较差，可以通过腹腔镜手术剥离并切除。在这个罕见病例中，通过腹腔镜同时切除了腹膜后肿瘤和成熟畸胎癌。
