【摘要】：目的分析乳头状肾细胞癌的临床特点及病理特征。方法回顾性分析6例乳头状肾细胞癌患者的临床资料,并与同期住院肾肿瘤(透明细胞癌、错构瘤、其他类型肾细胞癌)患者进行比较。结果乳头状肾细胞癌患者年龄41~68岁,均为男性。就诊时4例无症状,2例有肉眼血尿。肿瘤最大直径平均4.6 cm,未见多中心病灶。TNM分期T1aN0M04例,T1bN0M01例,T2N0M01例。术后病理肿瘤组织呈乳头状或管状结构排列,乳头中心及间质内有泡沫细胞浸润,有明显出血坏死。病理分型Ⅰ型4例,Ⅱ型2例。Fuhrman分级Ⅱ级3例,Ⅲ级3例。结论乳头状肾细胞癌好发于男性,影像学检查不具备恶性肿瘤特征,其确诊有赖于病理和免疫组织化学检查;临床分期均为I或Ⅱ期,就诊时无一例出现远处转移。其临床表现与其他肾细胞癌相似,但影像学表现、病理形态及生物学行为表现均与其他肾细胞癌有所不同。
[Abstract]:Objective to analyze the clinical and pathological features of papillary renal cell carcinoma. Methods the clinical data of 6 patients with papillary renal cell carcinoma were retrospectively analyzed and compared with those of hospitalized renal tumors (clear cell carcinoma, hamartoma, other types of renal cell carcinoma). Results the age of patients with papillary renal cell carcinoma was 41 ~ 68 years old, all of them were male. There were 4 cases of asymptomatic hematuria in 2 cases. The mean maximum diameter of the tumor was 4.6 cm. There were no multicentric lesions. TNM staging was performed in T _ 1bN _ 0M _ 01 and T _ 2N _ 0M _ 01. The pathological tumor tissues were arranged in papillary or tubular structure, foam cells were infiltrated in the center of papilla and interstitium, and hemorrhage and necrosis were observed. Pathological classification included type 鈪，
