A 25-year-old woman had a mass of approximately 65 cm × 33 cm × 102 cm, located in the left paraaortic area on CT scan. It was diagnosed as retroperitoneal malignant neoplasm on imaging. Afterward, open retroperitoneal tumor excision was performed. At laparotomy, the mass was carefully dissected from the ureter, renal artery, and aorta and excised as en-bloc. The pathological result was "myopericytoma." Histologically, the pathological findings characterized a pericytic neoplasm characterized by a perivascular growth of myoid tumor cells. In addition, there were uniform, oval-shaped cells with eosinophilic cytoplasm arranged in short fascicles around blood vessels. The cytologic atypia and mitoses were absent. There are many different tumors in the retroperitoneal area. Most of these lesions are malign nature. Nevertheless, for each benign and malign neoplasm, the preoperative imaging method is generally similar. This present case showed the significant findings of myopericytoma, a benign pathology located in the retroperitoneal area.
一名25岁女性在CT扫描中发现左腹主动脉旁区域有一个大小约为65 cm×33 cm×102 cm的肿块。影像学诊断为腹膜后恶性肿瘤。随后，进行了开放性腹膜后肿瘤切除术。在剖腹手术中，小心地将肿块从输尿管、肾动脉和主动脉上分离下来并整块切除。病理结果为“肌周细胞瘤”。组织学上，病理表现为一种肌样肿瘤细胞围绕血管呈血管周围生长的周细胞肿瘤。此外，还有均匀的、椭圆形的细胞，嗜酸性细胞质，围绕血管呈短束状排列。无细胞异型性和核分裂象。腹膜后区域有许多不同的肿瘤。这些病变大多数为恶性。然而，对于每一种良性和恶性肿瘤，术前影像学检查方法通常相似。本病例显示了肌周细胞瘤的显著特征，这是一种位于腹膜后区域的良性病理类型。
