Light micrograph of low-grade papillary urothelial carcinoma. The tumor is composed of numerous papillary fronds lined by 7 to 10 layers of urothelial cells lacking significant cytologic atypia (cell abnormality). The papillary cores contain blood vessels as well as aggregates of foamy histiocytes (lipid-laden macrophages).
