TL;DR: The aim was to develop a universally acceptable classification system for bladder neoplasia that could be used effectively by pathologists, urologists, and oncologists.

TL;DR: After progression to muscle-invasive disease, even during close follow-up the outlook was poor, as poor as for patients with primary muscle- invasive disease.

TL;DR: Five cases of benign epithelioid schwannoma that were in the subcutis and the neck of the urinary bladder are described and the benign nature of the lesions was evident, including small size, sharp circumscription, bland morphology, low proliferative activity and a benign clinical course after either marginal or intralesional excision.

TL;DR: It is concluded that diagnosis of bladder tumours requires both biopsy and cytological techniques, since they proved complementary in a number of cases.

TL;DR: Development of international guidelines for the diagnosis, treatment, follow-up, and prevention of low-grade Ta urothelial carcinoma of the bladder is discussed, with many grade A and B recommendations on the diagnostic workup and management of this disease given with level 1 and 2 evidence based on prospective randomized clinical trials of sufficient statistical power.
