				        	Papillary adenoma (PA) of kidney is defined as a lesion measuring less than 15 mm and featuring papillary or tubular architecture along with nuclei of low grade.Clear cell renal cell carcinoma (CCRCC) is the most common seen group of malignant neoplasms consists of cells with clear or eosinophilic cytoplasm.The coexistence of these two kinds of tumor is rare and was only reported in one piece of literature to date.We report a thought-provoking case in which CCRCC is coexisting with multiple PAs.The CCRCC shows no difference with other common cases while the PAs share the same clinical and pathological features with other ones and demonstrates no amplifying of 3,7 or 17 chromosome.However,the multiple PAs were neglected by imaging doctors and surgeons,and some tiny lesions were not found until the observation under microscope.This case reminds that patients accepting partial nephrectomy for CCRCC may have PAs,so attention should be paid to the image studies along with routine pathological examination of kidney for that there may exists two or more kinds of lesions.
