Cystic renal cell carcinoma (CRCC) is relatively rare; it represents a special subtype of renal cell carcinoma (RCC) associated with a low nuclear grade and stage and an excellent prognosis regardless of tumor size. However, CRCC is frequently misdiagnosed as a benign renal cyst because it shares similar clinical manifestations and imaging characteristics. In the present study, we retrospectively analyzed 67 CRCC cases treated at our center; we summarize patient prognosis and the clinical manifestations, imaging characteristics, treatment, and pathologic features of CRCC based on medical record data. To our knowledge, this represents the largest series of CRCC cases, and it includes four cases with other concurrent RCCs.
