摘要
目的探讨肾脏黏液性管状和梭形细胞癌的临床病理特征。方法回顾分析4例肾脏黏液性管状和梭形细胞癌患者的临床资料。女性3例,男性1例;年龄35~56岁,平均41岁;左肾2例,右肾2例;肾上极3例,肾下极1例;肿瘤直径3.5~6.5 cm,平均5.5 cm;无明显临床症状及体征,均为体检发现。B超检查提示,2例肾囊实性占位,为良性肿瘤;2例为厚壁型肾囊肿。CT检查提示,3例肾囊实性占位,为良性肿瘤;1例为厚壁型肾囊肿。2例行MR I检查提示,肾脏囊实性占位,为良性肿瘤。结果 4例患者均予手术治疗,术中发现肿块与肾组织的界限清楚,易分离;肿块呈囊实性,囊壁厚薄均匀,组织致密且内壁光滑。术后病理组织学检查示：2例为低度恶性上皮细胞肿瘤,1例为恶性肿瘤（透明细胞癌不排除）,另1例为肾脏黏液性管状和梭形细胞癌。结论肾脏黏液性管状和梭形细胞癌是一种具有良性肿瘤生长特性的低度恶性倾向的肿瘤。
Objective To explore the clinical and pathological characteristics of renal mucinous tubular and spindle cell carcinoma.Methods Clinical data of 4 patients including 3 female and 1 male aged from 35 to 56 were analyzed retrospectively.Among the 4 cases,two tumors were in the left side and two in right.Three tumors located in the upper part of kidneys,one in the lower part.The size of tumors ranged from 3.5 to 6.5 cm.There was no obvious symptom or physical sign in all cases and the tumors were detected during healthy examination.In B type untrasonography,two patients showed cystsolid tumor and two showed thick-wall cyst of kidney.In CT scan,three patients showed cystsolid tumor and one showed thick-wall cyst of kidney.In MRI scan,two patients showed cystsolid tumor.All the imaging examinations indicated the lump was benign.Results There were clear boundaries between the tumors and normal kidney tissue and the lesions were easy to be separated during operation.The tumors displayed globular appearance and were cyst-solid which capsule walls were uniformly think,pale and smooth.The freezing pathological slices suggested two low-grade cancers and one suspicious clear cell carcinoma.The final pathological diagnosis was renal mucinous tubular and spindle cell carcinomas.Conclusion Renal mucinous tubular and spindle cell carcinoma is a kind of low malignant tendency cancer with benign features.
