Abstract：Objective To study the clinical pathological characteristics and the diagnostic standards of papillary renal cell car-cinoma(RCC). Method Histopathologic and immunohistochemical changes of 5 cases of papillary RCC were compared with those of 70 cases of non-papillary RCC. Results Papillary RCC is a special renal cell carcinoma. The course of the disease is longer and slow. The fact that Papillary RCC has a better prognosis than conventional RCC suggests that it is a tumor with lower malignant potential. It is radiographic hypovascular. On gross appearance, the tumor is completely or predominantly well circum-scribed, often with a thick fibrous capsule, hemorrhage and variable cystic degeneration. The histologic architecture is papillary or tubupapilary. In the papillary core or space between papillae there is infiltration of foam cells. Other constant features of papillary RCC is hemorrhage and necrosis. Conclusions Papillary RCC differs from non-papillary RCC in clinical course, radiographic and pathologic morphology and biologic behavior.Therefore, it should be classified as an independent histological type of RCC.
