Primary retroperitoneal mucinous cystic tumors (PRMCT) are divided into 3 groups: benign, borderline malignancy, and malignant. We report a rare case of benign retroperitoneal mucinous cystadenoma of a 59-year-old Caucasian female who presented to our clinic with moderate intermittent left upper quadrant abdominal pain for several months, accompanied by early satiety, and unintentional weight loss of 10 pounds. An abdominal contrast-enhanced computed tomography (CT) scan indicated the presence of a 6.5 × 8.8 cm multilobulated mass in the left upper quadrant, characterized by a homogenous appearance with smooth margins. Upper endoscopic ultrasound and fine needle aspiration were performed. Cytology and histology results yielded rare inflammatory cells and debris with no cytological evidence of malignancy. The case was discussed at the hepatopancreatobiliary conference; the patient underwent a robotic resection of the mass with a gastric rim. Primary retroperitoneal mucinous cystadenomas are commonly managed by complete surgical excision. Robotic excision presents an alternative approach for handling this uncommon neoplastic lesion.
原发性腹膜后黏液性囊性肿瘤（PRMCT）分为3组：良性、交界性恶性和恶性。我们报告了一例罕见的59岁白种女性良性腹膜后黏液性囊腺瘤病例，该患者因左上腹中度间歇性腹痛数月前来我院就诊，伴有早饱感及体重无意减轻10磅。腹部增强计算机断层扫描（CT）显示左上腹有一个6.5×8.8 cm的多叶状肿块，表现为均匀外观，边缘光滑。进行了上消化道内镜超声检查和细针穿刺活检。细胞学和组织学结果显示有罕见的炎性细胞和碎片，无恶性细胞学证据。该病例在肝胆胰会议上进行了讨论；患者接受了机器人辅助肿块切除并切除了部分胃边缘组织。原发性腹膜后黏液性囊腺瘤通常通过完整的手术切除进行治疗。机器人辅助切除为处理这种罕见的肿瘤性病变提供了一种替代方法。
