The most common primary malignant renal tumor is renal cell carcinoma (RCC), which accounts for 3% of all adult malignancies. Bellini duct carcinoma or collecting duct carcinoma is an unusual rare variant of RCC. This histologically distinct tumor is very rare, with less than 100 cases reported in the literature, and accounts for approximately 1% of all malignant renal epithelial tumors. We report two cases of collecting duct carcinoma and highlight the rarity of these tumors and their similarity to RCC.
最常见的原发性恶性肾肿瘤是肾细胞癌（RCC），它占所有成人恶性肿瘤的3%。贝氏管癌或集合管癌是肾细胞癌一种罕见的特殊变体。这种组织学上独特的肿瘤非常罕见，文献报道不足100例，约占所有恶性肾上皮肿瘤的1%。我们报告两例集合管癌病例，并强调这些肿瘤的罕见性及其与肾细胞癌的相似性。
