Metastatic non-colorectal cancer of the anal canal is a rare entity.
To date, only four cases have been described in the literature. We present a 76-year-old man who was referred with an unusual perianal lesion. He had a history of renal cell carcinoma 7 years previously. Histologically, the lesion revealed clear cell carcinoma in keeping with metastasis. To our knowledge, this is only the second time a renal carcinoma metastasis to the anal canal has been identified.
