PUNLMPs are characterized by a homogenous monotonous appearance, normal to slightly enlarged nuclei and inconspicuous nucleoli. Mitotic figures are uncommon and, when present, are confined to the basal layer. The major distinction between PUNLMP and urothelial papilloma is thickening of the urothelium in the former.
