[Pathology of tumors of the urinary bladder, aspects and expectations of the histological report (TUR, cystectomy)].

Abstract

Urothelial tumors are among the most frequently occurring malignancies. The patients' clinical outcome can be diverse after recognition of the presence of the tumor. The result of the histology report (grade, histologic subtype, stage) makes remarkable impact on treatment strategies. There are innumerable papers (debates) in the literature concerning the best methods in classification, stage determination, application of immunohistochemical markers (to possibly avoid false negative, false positive results) and the use of molecular biological examinations. The authors attempt to draw attention on the everyday diagnostic difficulties of the "general pathologist", through their own experience and the latest reports of the literature.
