A case of oncocytoma, the radiological findings of which resembled a hemorrhagic renal cyst, is reported. Cyst fluid analysis demonstrated extremely high levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9). Preoperatively the lesion was regarded a malignant cyst, and radical nephrectomy was performed. Pathological diagnosis was renal oncocytoma with cystic degeneration. Although cystic change occasionally has been mentioned in oncocytoma, a high level of CEA and CA 19-9 in the cyst fluid of the cystic oncocytoma have not been reported. We discuss the variant forms of oncocytoma and tumor markers in the cyst fluid.
本文报告一例嗜酸细胞瘤，其影像学表现类似出血性肾囊肿。囊液分析显示癌胚抗原（CEA）和糖类抗原19-9（CA19-9）水平极高。术前该病变被视为恶性囊肿，并进行了根治性肾切除术。病理诊断为伴有囊性变的肾嗜酸细胞瘤。尽管嗜酸细胞瘤中偶尔会提及囊性变，但囊性嗜酸细胞瘤囊液中CEA和CA 19-9水平升高尚未见报道。我们讨论了嗜酸细胞瘤的变异形式及囊液中的肿瘤标志物。
