目的:探讨两种不同临床类型肾黏液性小管状和梭形细胞癌的临床特点。方法:报告2例不同临床类型肾黏液性小管状和梭形细胞癌患者的临床资料,进行对比分析,并复习有关文献。结果:例1为体检发现,无局部及远处转移,无病理性核分裂像,异型性小。例2以持续高热就诊,有局部及远处转移,病理性核分裂像常见,异型性明显。2例均行肾癌根治术,例1术后随访未见复发。例2患者于术后3个月死亡,此为国内首例报道因肾黏液性小管状和梭形细胞癌死亡者。结论:肾黏液性小管状和梭形细胞癌有两种不同临床类型,多数为低度恶性,亦存在恶性程度较高的病例,需区别对待。
Objective: To investigate the clinical features of two different clinical types of renal mucinous tubule and spindle cell carcinoma. Methods: The clinical data of 2 patients with different clinical types of renal mucinous tubule and spindle cell carcinoma were reported and analyzed. The related literatures were reviewed. Results: In case 1, physical examination showed no local or distant metastasis, no pathological mitosis, and atypia. Case 2 to high fever treatment, local and distant metastasis, pathological mitosis common, atypia obvious. 2 cases were treated with radical nephrectomy, no recurrence after a follow-up. Example 2 patients died at 3 months after surgery, which is the first case reported in China due to death of renal mucinous tubule and spindle cell carcinoma. Conclusions: There are two different clinical types of renal mucinous tuberculous and spindle cell carcinoma, most of them are low grade malignant. There are also cases with higher malignant degree, which should be treated differently.
