Tubulocystic renal cell carcinoma (TCRC) is a rare renal tumor. Patients are usually asymptomatic; it is usually detected incidentally, during imaging studies for Bosniak type III and type IV renal cysts. These tumors rarely metastasize. The role of targeted therapy in such rare tumors is still controversial. We report a case of TCRC initially presented as a Bosniak type II renal cyst and was discovered ultimately to be a metastatic disease. This type of presentation might broaden our understanding of this rare disease.
小管囊性肾细胞癌（TCRC）是一种罕见的肾肿瘤。患者通常无症状；通常在对博斯尼亚克III型和IV型肾囊肿进行影像学检查时偶然发现。这些肿瘤很少发生转移。靶向治疗在这类罕见肿瘤中的作用仍存在争议。我们报告了一例最初表现为博斯尼亚克II型肾囊肿，最终被发现为转移性疾病的TCRC病例。这种表现形式可能会拓宽我们对这种罕见疾病的认识。
