Abdominal Subcutaneous Metastasis from Sarcomatoid Renal Cell Carcinoma

Abstract

Subcutaneous metastases originating from genitourinary tract cancers are rare, especially for renal cell carcinomas. The most common sites for such metastases are the lung, liver, brain and bone. Subcutaneous metastases are considered ominous. We report a 78-year-old man who presented with a huge solitary mass over the suprapubic region of the abdominal wall. He had been diagnosed as a renal cell carcinoma with multiple pulmonary metastases. Treatment for the mass consisted of wide excision and continuing systemic interferon therapy. The patient died three months after the surgery, following a rapid local recurrence and general deterioration.
