Clear cell type renal carcinoma accounts for about 80% of all renal cell carcinomas. We present a 39-year-old male with clear cell renal carcinoma of the right kidney, stage I: T1 b (5 cm) N0 M0, who developed cutaneous metastases in the right submandibular region 28 months after nephrectomy. Our case is unique as i) the patient with stage I cancer (at the time of nephrectomy) presented with an isolated cutaneous nodule in a location distant from the primary site; ii) cutaneous nodule developed while being treated with pazopanib for metastatic lesions in the lung and adrenal; and iii) nivolumab and ipilimumab combination therapy decreased the vascularity of the nodule though it did not halt the nodule growth. Physicians should be knowledgeable about this rare clinical entity and its varied presentation. Further studies are necessary to determine optimal treatment, as the current therapeutic agents for metastatic renal carcinoma might not be adequate for cutaneous metastasis.
