Collecting duct renal cell carcinoma: two different clinical stages, two different clinical outcomes.
Collecting duct carcinoma (CDC) of Bellini is a rare variant of renal cell carcinoma. It tends to be more aggressive when locally advanced or when having distant spread on diagnosis. The only favorable prognosis factor is low-stage, low-grade, with disease-free survival reported up to 5 years. We reviewed our renal cell carcinoma database and found 2 cases of CDC, namely 1 young female with locally advanced disease with supraclavicular metastasis and a dismissal prognosis, and 1 male with localized disease with 10-year disease-free survival.
