OBJECTIVE: To report an additional case of collecting duct carcinoma of the kidney, known as carcinoma of Bellini. METHODS/ RESULTS: A 65-year-old male patient was admitted for left renal pain. An ultrasound scan showed a solid right renal mass. The patient underwent extended radical nephrectomy. Pathological analysis of the surgical specimen disclosed carcinoma of Bellini. The patient is asymptomatic 18 months postoperatively. CONCLUSIONS: Carcinoma of Bellini is an uncommon tumor type arising from the collecting duct cells and accounts for 0.5%-2% of all renal tumors.
