Bottom Line: The aim of this essay is the self assessment of the level of knowledge of the 2004 WHO classification of bladder neoplasms through a series of MCQs, each associated a short commentary.This paper is directed to all who are involved with the application of this classification at the anticancer research, diagnostic, prognostic and therapeutic levels, in particular to uropathologists, urologists and oncologists.

Figure 7: Papillary urothelial neoplasm of low malignant potential.

Mentions: Morphologically PUNLMP largely, though not completely, corresponds to grade 1 papillary carcinoma in the old WHO system (Figure 7). The tumour consists of delicate papillae with little or no fusion. The covering urothelium shows minimal if any architectural irregularity. Nuclei are roughly normal in size, lack significant nuclear hyperchromasia or pleomorphism. The chromatin is fine and nucleoli are inconspicuous. Mitoses are infrequent and basally located. These tumors have a significantly lower rate of recurrence than either low- or high-grade papillary carcinomas and a very low rate of stage progression [5,9]. In a review of published studies, Lopez-Beltran [5,8] found the mean tumour recurrence rate to be 36% and stage progression rate to be 3.7%.
