Cutaneous Metastases From Transitional Cell Carcinoma of the Renal Pelvis: A Case Report

Abstract

A 73-year-old female patient presented with left back pain. Computed tomography showed a mass around the left renal hilum and subcutaneous masses in her abdomen. She was referred to our hospital. Retrograde pyelography showed an upper urinary tract obstruction. Urinary cytology of the ureter was negative. Biopsy of the subcutaneous mass was performed, and the pathological findings showed transitional cell carcinoma. She was diagnosed with transitional cell carcinoma of the left renal pelvis with metastasis to the skin (cT4N0M1). She received combination chemotherapy, but the size of her skin lesions was increasing. Three months after admission, she died. Metastasis to the skin from the renal pelvis is very rare; only four cases have been reported. Our case is the first report on transitional cell carcinoma of the renal pelvic metastasizing to only the skin at presentation. We herein summarize this rare metastasis and discuss its clinical features and therapeutic management.
