Cytologic diagnosis of the intraepithelial and microinvasive cancers in the human urinary bladder and their histopathologic bases

Abstract

The cytologic morphology was studied with the patients of 12 nonpapillary, intraurothelial and microinvasive cancers and the histopathologic bases of the cancer cells were analysed. Though the histopa thologic and cellular pictures of many of intra-urothelial and microinvasive cancers simulated that of insitu cancer of uterine cervical cancer (small and uniform, hyperchromatic cancer cells), they comprised some varieties of morphology like as Bowen-like and Paget-like lesions.
