Tubulocystic renal cell carcinoma is an uncommon subtype of renal cell carcinoma that was only recently acknowledged by the World Health Organization. There is a relatively small collection of literature dedicated to the features and clinical course of this lesion. Despite its rarity, this diagnosis should remain in the differential for all cystic renal masses. We present a case report of tubulocystic renal cell carcinoma (TC-RCC) with remarkable similarity to cystic renal oncocytoma, highlighting the diagnostic challenges associated with this unusual renal malignancy.
肾小管囊性肾细胞癌是肾细胞癌的一种罕见亚型，直到最近才被世界卫生组织认可。关于这种病变的特征和临床过程的文献相对较少。尽管它很罕见，但在所有肾囊性肿块的鉴别诊断中都应考虑到这种诊断。我们报告一例与囊性肾嗜酸细胞瘤极为相似的肾小管囊性肾细胞癌（TC-RCC）病例，突出了这种不寻常的肾恶性肿瘤相关的诊断挑战。
