目的 提高对肾脏炎性肌纤维母细胞瘤的认识。 方法 报告 1例发生于肾脏的炎性肌纤维母细胞瘤的诊治资料。患者男性, 30岁,无临床症状,体检发现肾脏占位性病变。实验室检查未见异常。B超示左肾中上部外侧有 4. 5cm×3. 7cm边缘清楚、内部回声不均之实性肿物。CT示该肿物与正常肾组织值相近。MRI增强扫描示肿物不均匀强化,较正常组织信号稍低,初步诊断肾癌。 结果 行肾切除术,病理示瘤组织由梭形纤维细胞组成,免疫组化染色示Vimentin、SMA、HHF35均为阳性。诊断为肾脏炎性肌纤维母细胞瘤。随访 54个月,未见肿瘤复发和转移。 结论 肾脏炎性肌纤维母细胞瘤为少见的良性或低度恶性肿瘤,临床无特异性诊断方法,确诊依靠病理,手术治疗时先送病理,以避免误切肾脏。
Objective To improve the understanding of renal inflammatory myofibroblastic tumor. Methods One case of inflammatory myofibroblastic tumor in the kidney was reported. Male patient, 30 years old, no clinical symptoms, physical examination found kidney lesions. Laboratory tests showed no abnormalities. B ultrasound showed that the left upper middle of the kidney 4. 5cm × 3. 7cm clear edge, uneven internal echo of solid tumors. CT showed the tumor and normal renal tissue values are similar. MRI enhanced scan showed uneven enhancement of the tumor, slightly lower than the normal tissue signal, the initial diagnosis of renal cell carcinoma. Results Nephrectomy, pathological tumor tissue composed of spindle fibroblasts, immunohistochemical staining showed Vimentin, SMA, HHF35 were positive. Diagnosis of renal inflammatory myofibroblastoma. Follow-up 54 months, no tumor recurrence and metastasis. Conclusions Kidney inflammatory myofibroblastoma is a rare benign or low grade malignant tumor. There is no specific diagnosis in clinic. The diagnosis depends on the pathology. When the operation is performed, the pathology is first sent to avoid the wrong-cutting of the kidney.
