One of the rarest tumors involving the urinary bladder is the pheochromocytoma. A case of pheochromocytoma of the urinary bladder in a young female suffering from headache and cystitis for many years is reported. Twenty-four hour urine VMA was normal. The patient was never hypertensive except during surgical manipulation of the tumor. Biopsy of the bladder resulted in massive hemorrhage.

OBJECTIVE to develop an experimental model of exposure to tobacco burning (cigarette) products to assess the effects of its chronic use in relation to cancers of the bladder. METHODS the animals were chronically exposed to the burning tobacco products in a semi-open chamber to simulate smoking. Thirty young Wistar rats were divided into two groups: one with 20 animals simulating smoking for s...

OBJECTIVE The purpose of this study was to evaluate the effectiveness of contrast-enhanced sonography in comparison with conventional sonography in differentiating muscle-infiltrating and superficial neoplasms of the urinary bladder. SUBJECTS AND METHODS Conventional and contrast-enhanced sonography were performed on 34 consecutively registered patients with bladder tumors. All examinations w...

Activating mutations occur in the promoter of the telomerase reverse transcriptase (TERT) gene in 66% of muscle-invasive urothelial carcinomas. To explore their role in bladder cancer development and to assess their utility as urine markers for early detection, we sequenced the TERT promoter in 76 well-characterized papillary and flat noninvasive urothelial carcinomas, including 28 pTa low-grad...

OBJECTIVES Neuroendocrine tumors (NET) are cancers found in the bronchopulmonary tract, where they were first described in 1926. The tumors are associated with poor prognosis due to their high metastatic potency even after radical treatments associated with other neo- or adjuvant therapies. NET of the urinary bladder is a rare tumor and accounts for 0.5% of bladder tumors. METHODS The study...

Lymphoepithelial - like carcinoma, is rarely recognized in the urinary bladder and less commonly occurs with papillary transitional cell carcinoma i.e. mixed pattern. Also, less uncommon is the occurrence of carcinoma in situ changes in the adjacent urothelium of these tumors. Here, a case of lymphoepithelial – like carcinoma and papillary transitional cell carcinoma associated with carci...

discussion bladder over-distention and spontaneous bladder rupture, although very rare in ham/tsp, should be considered in a differential diagnosis of bladder rupture, especially in patients with a history of htlv1. introduction spontaneous bladder rupture is a rare manifestation of hyporeflexic bladder due to ham/tsp( human t-cell lymphotropic virus type 1 (htlv1) associated myelopathy/tropica...

μalakoplakia is a rare inflammatory condition of the urogenital tract. the most frequently affected organ is urinary bladder. this condition has features of a granulomatous inflammation, the pathogenesis of which is not well understood. in this study, we presented a case of urinary bladder malakoplakia associated with advanced obstructive uropathy and renal failure.
