[Cutaneous and gynecologic metastases disclosing renal-cell carcinoma: the diagnostic and therapeutic implications].

The spread of is uncommon renal cell carcinoma to the female genital system it is even more uncommon to observe metastasis or its symptoms or signs, masking or preceding the clinical manifestations of the primary lesion. In the course of nephrectomy due to renal tumor, the early ligation of the gonadal vein during the control maneuvers of the vascular pedicle can reduce the risk of posterior genital metastasis. Similarly, the skin is an uncommon site of metastasis. The appearance of cutaneous metastasis from renal cell carcinoma may precede the detection of the underlying tumor, although most of the cutaneous metastases are observed after the primary lesion has been detected. In patients with solitary skin metastasis and no evidence of spread to other organ systems, nephrectomy and excision of the metastatic lesion have permitted a survival of 35% at 5 years.
