Bladder masses are represented by either benign or malignant entities. Malignant bladder tumors are frequent causes of disease and death in western countries. However, in children they are less common. Additionally, different features are found in childhood, in which non epithelial tumors are more common than epithelial ones. Rhabdomyosarcoma is the most common pediatric bladder tumor, but many...

For years, Rhode Island (RI) has had the greatest incidence of bladder cancer in the United States for both men and women. In fact, compared with the United States (US) overall, all of the New England states and New Jersey have disproportionately elevated bladder cancer rates. (Figure 1) From 2002-2006, the age-adjusted incidence of bladder cancer for men was 53.1/100,000 in Rhode Island versus...

Restaging, or second transurethral resection (TUR), is essential to successful management of high-risk, non-muscle-invasive bladder cancer. Here we review the relevant literature documenting the role of restaging TUR. Cohort and randomized studies show that restaging TUR detects more tumors than initial TUR, improves clinical staging, and reduces the frequency of early tumor recurrences. Our co...

Urachal carcinoma is a rare, aggressive malignancy accounting for less than 1% of bladder neoplasms. These tumours are usually adenocarcinomas and occur at the dome or anterior wall of the bladder. They often escape early clinical detection, growing for prolonged periods prior to diagnosis, resulting in local invasion and systemic spread before therapeutic intervention is initiated. We present ...

Out of all the different types of neoplasms affecting the stomach, gastric carcinomas with Osteoclast-like Giant Cells (OGC) is one of the most uncommon. Although OGC are typically found in osseous neoplasms and tumors of the tendon sheath, few cases of extra-skeletal neoplasms with OGC have been documented. These typically involve organs such as the pancreas, gall-bladder, kidney, and breast. ...

There is a well-documented relationship between urinary bladder diverticula and intradiverticular neoplasms. The great majorities of these tumors are urothelial carcinomas, but may also be of glandular or squamous type. Sarcomas occurring within bladder diverticula are exceptionally rare and highly malignant lesions, with only 20 well documented cases published in the literature to date (includ...
