RESUMEN
Three cases of synchronous primary bilateral macronodular adrenal hyperplasia(PBMAH) and renal cell carcinoma (RCC) in the Department of Urology of Peking Union Medical College Hospital were retrospectively reviewed. The clinical features, imaging features, treatment methods and pathological features of these patients were analyzed. It was found that the genetic relationship between synchronous PBMAH and RCC needs further research. And RCC is easy to be misdiagnosed. We should pay high attention to imaging features to find out whether there are lesions in bilateral kidneys when we deal with bilateral adrenal lesions. Laparoscopic approach is recommended for PBMAH and RCC. Total or partial nephrectomy should be performed according the tumor size and location of the renal mass. Patients with PBMAH should be closely followed up after bilateral adrenalectomy to avoid delay in diagnosis or treatment of RCC.
