[Carcinoma of Bellini's ducts: apropos of a case].
OBJECTIVE
To report an additional case of collecting duct carcinoma of the kidney, known as carcinoma of Bellini.


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.
