Isolated adrenal metastasis of bladder cancer, particularly the bilateral, is quite rare. Systemic chemotherapy is the treatment of choice for metastatic urothelial carcinoma. However, despite initially promising response rates of approximately 45%-71%, most tumors eventually show progression, and the median survival time following chemotherapy regimen is approximately 14-15 months. Recently, f...

Urothelial carcinoma is a common malignant neoplasm that has a poor prognosis and a high frequency of recurrence and metastasis. Constant disease surveillance with periodic and long term cystoscopy examination is necessary for management of the disease. However, the monitoring and therapy regimen is expensive, incurring a massive burden to patients and the government. Therefore, the development...

BACKGROUND Optical coherence tomography (OCT) has become a promising diagnostic tool in many medical fields. In particular, noninvasive real-time optical biopsy of internal organs is one of the most attractive applications of OCT, enabling in situ diagnosis of carcinoma at an early stage. We used an ultra-high speed OCT system for real-time three-dimensional (3D) imaging of three excised specim...

Urothelial carcinoma of the bladder and upper tract pose significant diagnostic and therapeutic challenges. White light endoscopy plays a central role in the management of urothelial carcinoma but has several well-recognized shortcomings. New optical imaging technologies may improve diagnostic accuracy, enhance local cancer control, and better stratify treatment options. Confocal laser endomicr...

Vulvar metastasis of urothelial carcinoma of the bladder is a very rare entity; few cases are reported in the English literature. In this paper, we describe the clinical and pathological characteristics, evolution, and treatment of a patient with vulvar metastasis of urothelial carcinoma of the bladder followed by a brief review of the reported cases in the literature.

A case of malakoplakia and papillary urothelial carcinoma of the urinary bladder is reported. In this case, malakoplakia was an incidental finding in a biopsy of the urinary bladder of a 74-yr old female, who presented with hematuria. The biopsy showed a low-grade papillary urothelial carcinoma in close association with malakoplakia. This is a rare association of these lesions.

Adult rhabdomyosarcoma (RMS) in the urinary bladder is rare, and is the subject of case reports and small series. It consists of sheets of small round blue cells with high nuclear cytoplasmic ratio, brisk mitosis and apoptosis. In this study, we reported one case of pure rhabdomyosarcoma and two cases of urothelial carcinomas with extensive rhabdomyosarcomatous differentiation. In addition, the...

PURPOSE Radical changes in both expression and glycosylation pattern of transmembrane mucins have been observed in various malignancies. We and others have shown that MUC1 and MUC4, two transmembrane mucins, play a sentinel role in cell signaling events that drive several epithelial malignancies. In the present study, we investigated the expression profile of MUC1 and MUC4 in the non-neoplastic...

Terminal differentiation of urothelium is a prerequisite for blood-urine barrier formation and enables normal sensory function of the urinary bladder. In this study, urothelial differentiation of normal human urothelium and of low and high grade papillary urothelial carcinomas was correlated with the expression and localization of purinergic receptors (P2X3, and P2X5) and transient receptor pot...
