Malignant Non-Urothelial Neoplasms of the Urinary Bladder: A Review
European Urology, 2003Non-urothelial bladder tumors frequently present a diagnostic and therapeutic challenge. We review the peer-reviewed literature to summarize the available evidence on the etiology, diagnosis and optimal management of malignant non-urothelial bladder tumors.A comprehensive MEDLINE database search was performed.

Urinary bladder MR imaging. Part II. Neoplasm.
Radiology, 1985The potential of magnetic resonance (MR) imaging for the evaluation and staging of bladder tumors was analyzed in 15 patients (11 cases of transitional cell carcinoma, two adenocarcinomas, one leiomyosarcoma, and one leiomyoma). Neoplasms were characterized by size, site, and growth pattern, and the accuracy of the staging was compared with the results

Neoplasms of the Urinary Bladder: Radiologic-Pathologic Correlation
RadioGraphics, 2006In the United States, primary bladder neoplasms account for 2%-6% of all tumors, with bladder cancer ranked as the fourth most common malignancy. Ninety-five percent of bladder neoplasms arise from the epithelium; the most common subtype is urothelial carcinoma, which accounts for 90% of cases.

Current status of urinary cytology in the evaluation of bladder neoplasms
Human Pathology, 1990Pathologic examination of urinary specimens is increasingly recognized as an essential component of detection and monitoring for patients with bladder neoplasms. Among the available techniques, urinary cytology is the most useful. The current status of urinary cytology can be summarized as follows: 1.

Classification and Differential Diagnosis of Neoplasms, Urinary Bladder, Rat [PDF]
, 1986 Bladder cancer in rats is a widely used and valuable model in carcinogenesis research. Considerable interest has also been centered on this tumor as an end-point in carcinogenesis testing and the resulting impact upon regulation of chemicals, such as cyclamate, saccharin, and melamine.

AgNORs in benign, borderline and transitional cell neoplasms of the urinary bladder
APMIS, 1998Argyrophilic nucleolar organizer regions (AgNORs) were studied in 106 tissue samples from the urinary bladder (6 normal transitional epithelium, 5 cystitis, 12 hyperplastic, 14 dysplastic lesions, 12 carcinoma in situ, 4 transitional cell carcinoma grade 0, 12 grade 1, 15 grade II and 12 grade III) to evaluate their role in differentiating benign ...

Stromelysin-3 expression in noninvasive and invasive neoplasms of the urinary bladder
Human Pathology, 2000Stromelysin-3 (ST-3) is a protease frequently expressed by fibroblasts surrounding invasive carcinomas. Based on its expression in some cases of breast carcinoma-in-situ, it has been thought to indicate a higher likelihood for subsequent invasion in preinvasive lesions.
