title: [Metachronous solitary contralateral adrenal metastasis of primary renal carcinoma: report of a new case].
abstract: OBJECTIVE
  To report a case of solitary metachronous contralateral metastasis of a renal carcinoma that had been previously resected.
  
  
  METHODS
  A 63-year-old male that had previously undergone a right radical nephrectomy due to renal carcinoma is presented. The patient's left breast was found to be slightly larger at the control evaluation 24-months postoperatively. Analytical and hormonal studies showed no significant findings except for a serum creatinine value of 1.75 mg/dl. However, a CT scan showed a left adrenal nodule of 3 cm. After 6 months of watchful waiting, the nodule had increased to 4.3 cm. A CT-guided fine needle punction aspiration biopsy demonstrated a malignant lesion and a left adrenalectomy was performed.
  
  
  RESULTS
  Histopathological analysis of the surgical specimen showed adrenal metastasis of clear cell renal carcinoma. At 21 months' follow-up after adrenalectomy, there is no evidence of recurrence of the metastasis.
  
  
  CONCLUSIONS
  This type of lesion is uncommon. We emphasize the importance of the analytical and hormonal studies, as well as CT and FNPA, in the diagnosis of this adrenal pathology. Like other authors, we advocate performing adrenalectomy in these cases.
