Tubulocystic Renal Cell Carcinoma: A Great Imitator

[摘要] 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.
