The medical literature refers to a small percentage (around 4%) of the incidence of oncocytomas synchronous with other kidney tumors as renal cell carcinoma, pelvic urothelial carcinoma, angiomyolipoma etc. Papillary adenoma is one of those tumors that may rarely coexist with oncocytoma. In this study, we present a case of 69-year-old male patient with synchronous occurrence of concomittant unilateral renal oncocytoma and papillary adenoma, and urothelial carcinoma in bladder. To the best of our knowledge, this is the first case report combining those urinary tumors in the medical literature. http://pubs.sciepub.com/ajmcr/2/11/7/ajmcr-2-11-7.pdf Synchronous urinary tract urothelial carcinoma oncocytoma papillary adenoma
