CARRION LOPEZ, Pedro et al. Bellini duct carcinoma: Report of two cases. Arch. Esp. Urol. [online]. 2008, vol.61, n.3, pp.424-427. ISSN 0004-0614.

Objective: We report two cases of collecting duct carcinoma that were diagnosed in our hospital in a six-month period. Methods/Results: The first case was a 75-years-old woman showing in CT scan a mass in the left kidney which infiltrated perinephric fat. The second case was a 72-years-old that showed in a CT scan a right renal pelvis lesion, involving inferior vena cava and renal vein. After surgical resection by radical nephrectomy in both cases, we confirmed the histological diagnosis of collecting duct carcinoma. Conclusions: Collecting duct carcinoma is a rare variant of renal cell carcinoma which originates from the epithelium of the collecting tubule. It is characterized by both its aggressiveness and peculiar histological and inmunohistochemical diagnosis, that separates it from the rest of renal tumors.

Keywords : Collecting duct carcinoma; Renal tumor; Inmunohistochemic.
