    The 2004 WHO classification of bladder tumors: A summary and commentary

    No full text
    The key points of the latest World Health Organization (WHO) classification of non-invasive urothelial tumors are the following: the description of the categories has been expanded to improve their recognition; a tumor with particularly good prognosis (papillary urothelial neoplasm of low malignant potential) no longer carries the label of 'cancer'; it avoids the use of ambiguous grading such as grade 1/2 or 2/3 (as done in the 1973 WHO classification); the group of noninvasive high-grade carcinoma is large enough to virtually contain all those tumors having biological properties similar to those seen in invasive urothelial carcinoma, and a similarly high level of genetic instability. This scheme is meant to replace the 1973 WHO classification, but the use of both the 1973 and the latest WHO classifications is recommended until the latter is sufficiently validated

    Dr. Rodolfo Acun\u303a recounts his work in Chicano studies, teaching, and research

    Dr. Rodolfo Acun\u303a talks about his pioneering effort starting the first Chicano Studies department at California State University, Northridge. Acun\u303a reflects on his teaching career, his research, and writings about cultures in conflict. He talks about writing several books including "Occupied America: A History of Chicanos" and "Corridors of Migration." Acun\u303a describes personal experiences that contributed to his radicalization. He criticizes academic and government policies which have denied Chicanos access to education and opportunity. He describes his research methods and the purpose of his histories, his emphasis on Chicano studies, and prospects for the future of Chicano studies. Acun\u303a is interviewed by Michigan State University professor Dionicio N. Valde\u301s

    Microcystic urothelial carcinoma: morphology, immunohistochemistry and clinical behaviour.

    AIMS: To report on the clinicopathological features of 20 cases of microcystic urothelial bladder carcinoma. METHODS AND RESULTS: The extent of microcystic component varied from 50-100% of the specimens. The cysts were round-oval and of varying sizes; the periphery of large cysts was frequently punctuated by many smaller cysts. The cysts were lined by urothelial, low columnar cells or by a single layer of flattened epithelium of low-intermediate nuclear grade. Focal high-grade conventional urothelial carcinoma was present in eight cases. Immunohistochemistry demonstrated variable positivity for cytokeratins 7 and 20, MUC1, MUC5AC, p63 and GATA3. Extent of expression of Ki67, p53 and p27kip1 ranged from 20-60%, 10-40% and 10-30% of cells, respectively. On follow-up, 11 patients died of disease at 11-56 months and three patients were alive with disease at 26-37 months. Univariate survival analysis showed no differences for microcystic carcinoma versus conventional urothelial carcinoma (P = 0.548). CONCLUSIONS: Microcystic urothelial carcinoma may pose diagnostic difficulties, especially in limited biopsy samples, where it may be mistaken for cystitis glandularis or adenocarcinoma of the bladder. Histological features, clinical history and appropriate immunohistochemical studies should help to distinguish it from its mimics. Aggressiveness seems to be related to higher stage at diagnosis
