At high magnification, the plasmacytoid appearance can be easily appreciated. Most cases have co-existing conventional high-grade urothelial carcinoma. At cystoscopy, an exophytic tumor mass may not be visible and the only positive findings may be coarse mucosa with thickening of bladder wall. The outcome is generally poor due to high-grade and high stage at presentation. Mai KT et al, Eur Urol. 2006 Nov; 50(5):1111-4.return to Variants of Urothelial Carcinoma
