Аннотация
BACKGROUND: Renal cell carcinoma developing metastases in the bladder is rare. Bladder metastasis due to a papillary type of renal cell carcinoma is rarer. Such metastases could be synchronous or metachronous.
CASE PRESENTATION: Here we present a 55-year-old female patient with haematuria who underwent left nephro-ureterectomy for a suspected urothelial tumour. Histopathology revealed it to be a type 2 papillary renal cell carcinoma. Eighteen months later, she developed metachronous bladder metastasis of the papillary renal cell carcinoma which was treated with total cystectomy. Currently, she is on interferon therapy.
CONCLUSIONS: These bladder metastases from renal cell carcinoma could be due to drop metastases, lymphatic spread or haematogenous spread. The exact mechanism in a given case appears to be unpredictable.
