Multifocality in renal tumors is a rare occurrence, but not unheard of. Commonly the different foci correspond to the same histological pathology, however co-existence with other renal lesions, including both malignant and benign tumors, have also been reported. Here we present a 57-year-old male, ex-smoker who exhibited four distinct histological tumors in an ipsilateral kidney; multilocular cystic clear cell renal cell carcinoma (RCC) of low malignant potential, clear cell papillary RCC, renal oncocytoma, and renomedullary interstitial cell tumor. To our knowledge this is the first time these four tumors were found in the same patient, let alone the same kidney.
肾肿瘤中的多灶性情况罕见，但并非闻所未闻。通常不同病灶具有相同的组织病理学特征，不过也有报道称其可与其他肾脏病变并存，包括恶性和良性肿瘤。在此，我们报告一例57岁男性，既往吸烟者，其同侧肾脏出现了四种不同组织学类型的肿瘤；低恶性潜能的多房囊性透明细胞肾细胞癌（RCC）、透明细胞乳头状RCC、肾嗜酸细胞瘤和肾髓质间质细胞瘤。据我们所知，这是首次在同一患者身上发现这四种肿瘤，更不用说在同一侧肾脏了。
