Diagnosis: Urothelial carcinoma of the bladder, conventional and micropapillary variant, high-grade, pT2.    

            Comments: Micropapillary is a distinct variant of urothelial carcinoma. Characteristically, invasive micropillary carcinoma exhibits small, tight nests of cells within tissue retraction spaces. May be pure or admixed with conventional urothelial carcinoma. Presence of even minor proportion of the micropapillary component can affect survival. It is invariably high grade and often present at advanced stage.
