Collecting duct carcinoma (CDC), also known as Bellini duct carcinoma, is an extremely rare and highly aggressive subtype of renal cell carcinoma. Most patients present with metastasis at the time of diagnosis, and the prognosis for CDC patients is generally poor. Surgery is the primary treatment approach. In this article, we report a case of CDC presenting primarily with hematuria and provide a comprehensive review of the published literature concerning its diagnosis, treatment, and prognosis. The aim is to enhance understanding of this rare renal malignancy by elucidating its clinical and pathological characteristics and supplementing relevant treatment experiences.
