Renal tumors include several categories, the most frequent being clear cell renal cell carcinoma, papillary renal cell carcinoma, chromophobe carcinoma, oncocytoma, adenoma and angiomyolipoma. The aim of the study was to analyze the incidence of renal tumors in autopsy material. Among 3512 autopsies performed in our institution in the last decade, we found 97 post mortem examinations in which 108 renal tumors were detected. The most frequent diagnosis was adenoma (53 cases, 49.1%) and, among cancers, clear cell carcinoma (20 cases, 21.1%) followed by papillary carcinoma (17 cases, 15.5%). Less frequent lesions were angiomyolipoma (4 cases), oncocytoma (4 cases), unclassified renal cell carcinoma (3 cases), medullary fibroma (5 cases) leiomyoma (1 case) and urothelial carcinoma (1 case). The adenomas were significantly more frequent in cases of kidneys with chronic fibrosis. When comparing the present series to surgical material from a similar period, of note is that 44% of renal carcinomas in the autopsy series were papillary, but only 9.4% were papillary in the surgical material.
肾肿瘤包括几类，最常见的是透明细胞肾细胞癌、乳头状肾细胞癌、嫌色细胞癌、嗜酸细胞瘤、腺瘤和血管平滑肌脂肪瘤。本研究的目的是分析尸检材料中肾肿瘤的发病率。在过去十年里，我们机构进行的3512例尸检中，我们发现97例尸检检测出108个肾肿瘤。最常见的诊断是腺瘤（53例，49.1%），在癌症中，透明细胞癌（20例，21.1%）其次是乳头状癌（17例，15.5%）。较少见的病变是血管平滑肌脂肪瘤（4例）、嗜酸细胞瘤（4例）、未分类肾细胞癌（3例）、髓质纤维瘤（5例）、平滑肌瘤（1例）和尿路上皮癌（1例）。在患有慢性纤维化的肾脏病例中，腺瘤明显更常见。将本系列与同期手术材料进行比较时，值得注意的是，尸检系列中44%的肾癌是乳头状的，但手术材料中只有9.4%是乳头状的。
