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 3: Reactive atypia.

Mentions: In the presence of acute and/or chronic inflammation, the urothelium shows a wide range of reactive changes (Figure 3). There is usually a history of instrumentation, infection or treatment with intravesical agents. Some patterns of atypia are associated with specific aetiologies. In reactive atypia the epithelium may or may not be thickened. Although a thickened epithelium is typically associated with a reactive process, carcinoma in situ can also produce a thicker than normal epithelium. Nuclei are uniformly enlarged, vesicular, and may have prominent usually centrally located nucleoli. Mitoses may be frequent and are in the lower epithelial layers. Inflammation is almost always present [2].
