Solitary fibrous tumor (SFT) is a rare mesenchymal tumor occurs in various sites. Malignant SFT in retroperitoneum is extremely rare.
We report a case of malignant retroperitoneal SFT in a 59-year-old man presented with right flank pain for 1 month.
DIAGNOSES, INTERVENTIONS AND OUTCOMES: A laparotomy and resection of the tumor were performed, the histopathologic and immunohistochemical findings were consistent with malignant retroperitoneal SFT. No adjuvant treatment was performed, and the patient had no signs of recurrence or metastasis at the 12 months follow-up.
Complete surgical excision is the basic treatment principle for malignant retroperitoneal SFT. The histologic features and the Ki-67 label index are helpful for the diagnosis of malignant SFT.
孤立性纤维瘤(SFT)是一种罕见的间叶组织肿瘤,可发生于多个部位。腹膜后恶性SFT极为罕见。
我们报告一例59岁男性的腹膜后恶性SFT病例,该患者出现右侧腰痛1个月。
诊断、干预及结果:进行了剖腹手术并切除肿瘤,组织病理学和免疫组化结果与腹膜后恶性SFT相符。未进行辅助治疗,患者在12个月的随访中无复发或转移迹象。
完整手术切除是腹膜后恶性SFT的基本治疗原则。组织学特征和Ki-67标记指数有助于恶性SFT的诊断。
